congstar Reviews 

Really poor communication and zero customer loyality with the customer. I extended my contract in October last year after being 5 years with them and turned out that I had an open invoice of 30 euros, since Nov. per which I was not aware of, they have my SEPA and all the means to charge me that extra unpaid invoice or simply talk to me. But guess what? they decided to terminate my contract and charge me the rest of the months to come for a service that I never used, which is ridiculous.

Zero customer loyalty, I was with them for about 5 years, and all of the sudden, they just kicked me out.
Please talk to your customer.

I got a Congstar homespot Oct. 2019. I cancelled contract August or September 2022, but Congstar is still taking 30€ monthly Payments from my Bank Account. I cannot or couldn't use the Hotspot card since I moved out from the Apartment it is registered for use.

I'm using the homespot 200 contract with the Alcatel HH40V LTE-Router which should provide up to 50 mbit/s download rates. In reality, I get less than 5 mbit/s when the router is placed in the kitchen with two sides of the room consisting mostly of glass and the laptop standing right next to it. When I open the door to the terrace it sometimes improves to almost 10 mbit/s. I understand that congstar does not guarantee a minimum download rate and they're well advised not to, however, this is of course deeply unsatisfying and does not allow basic streaming at a resolution that doesn't make me want to rip my eyes out.

Edit 27.09.2022:
I contacted customer service following the link as suggested. Weeks later, they haven't gotten back to me. The download rates are still horrible. It frustrates me that I am being told that the signal depends on building and location conditions. As I pointed out, two sides of the room are mostly glass and an LTE provider, in my opinion, should foresee the possibility that customers live in enclosed spaces. In fact, outside we get better reception, just that a router shouldn't stand outside. Anyway, this is simply not working anywhere close to how it should be.

I was calling customer service today to get help as I was unable to load money on to my account ( prepaid cards were sold out, couldnt download the app with a foreign mobile and wasnt able to recharge on their side as you need a fast
internet connection and you cant use wifi...so if your data pack is used up..how to magically get this done???) ...the lady was super unfriendly and impatient...either they are trained like this or they hire low class people without softskills...she simply hung up on me without suggesting a solution...unbelievable!!!

Rip-off merchants.

1) Not enough GBs of data allowance on Prepaid. Considering it's 2022, Congstar seems to be run by 20th Century techies, who probably salivate over the sound of a 90s modem.

2) 4 EUR for a reminder due to a payment not clearing. Only by chance did I notice this by happening to log into my account. God knows what the charge would've ended up as otherwise.

Worst customer service and worst internet provider I have ever dealt with. I have not had internet for a week. They called a technician three times to fix my connection. Unfortunately, the technician is scheduled for a different day or time than stated, which means the technician will not arrive at all or will arrive several hours earlier than scheduled. Unfortunately, not everyone has the opportunity to wait 6 hours at home and stare at the phone and the router. I already wanted to terminate the contract without notice - a special situation. I was told I couldn't do that even though the errors were their fault.
Congstar: please bring this chaos and lack of professionalism in your company under control.
Everyone else: it is better to find another internet provider right away.

This idea and the tariffs are seemingly good. But their hotspot/connection simply doesn't work. You get disconnected from the wifi network constantly and the internet connection is super unstable. Even my iPhone does a much better job at it. I don't know how this is legal to sell such an unfinished product.
Avoid at all costs!

Worst customer experience, customer service, and telecommunications company. If you can avoid hiring anything with them, you are doing a great favor to yourself. I upgraded my tariff to a superior. However, after some days, I decided I no longer need it, so I filled the Widerrufsformular in November, and sent it to them. After a week without getting any reply, they communicate me that they cannot proceed with my Wiederrufsformular and restore my previous tariff, so they keep pushing me to go to another tariff and to keep paying invoices. They do not let me cancel and push me to request termination, so they can issue another invoice. Their customer service agents wont even bother to read your messages if you write them in English (cant confirm if its the same if you write them in German, but as far as I can see in other reviews, thats the case too). Their support agents will just pass the buck and repeat you that you have to pay. They will never try to help you or pay attention to anything what you say. After several messages, one agent is willing to help and confirm he will cancel the invoices, but they need to be issued first (???). They cancelled two of my invoices, but now they issue another in February, after the Widerrufsformular was sent in November, and their agents will only repeat I have an open invoice and need to transfer the amount to their account. One star is way too much!!

You will get the money for this invoice Congstar. But I assure you, I will never use any of your services again, and I will actively urge all of my contacts and companies im in contact with, to refrain of using your services.

Edit: After contacting them on the phone, The agent was willing to help me. They recognized it was their mistake and will provide a full refund. I will update once I can confirm the refund

Not only do their homespot devices not work well (we're constantly unplugging it), but the contract is thievery. We didn't have issues in the first 14 days, of course, and this is the last point in which you can get out of the contract. We needed internet quickly and wanted to move with it and are paying for it now. The cost is ridiculous compared to dsl or a landline and to get more data is outright theft. For those of us working at home during Covid a company charging fees like this should be regulated by the government. Read the fine print before signing a contract with this company.

Probably the best operator to use Telekom net without selling your organs to pay the bill. In the 5g era you should at least give the 50mbit/s option for free, this would convince me to stay.

there is nothing in english 'in the app. Not even how to top-up'. the official answer to that was "we are a german company". Very sad for a european company of that scale
(I had to edit the comment because there is no option to reply to the response, and it seems that it was not clear. In ' ' what I added afterwards)

I bought two mobiles from them and without problems, even with the contract there was no unfair discount, everything is good

Very bad experience. They are not accepting foreign passports for legitimation. No money back. Waste of a sim card,money and time.

Customer service was not helpful.

VERY COMPLICATED PROCEDURE TO REGISTER POSTPAID SIM CARD

I like Congstar for their customer support. They never tried to sell me anything, they just replied to my questions. They do have English support that this has helped me A LOT, and they are honest with what they can offer.

In the last months me and my partner have made the mistake to choose Congstar as our provider.
We had many issues with their customer service, every time we talked to them, we got mixed information, and they don´t take any responsibilities of their mistakes.
We are the only one paying for their mistakes!
My partner was mocked by a manager and their customer service never really apologised to us about the awful situation, we never got treated like that by a customer service in our entire life.
We sent them email and they don´t address all the questions we asked, ignoring us. The situation is getting frustrating because they don´t give us options or anything to try to make the situation better for us.
It seems that they don´t care about us. I am sure that most of the people in Congstar are good people and I would not normally write reviews like this. However, they have made our situation even more stressing and they ignore us when we ask questions, only answering what they want.

If I could, I would give 0 stars to their customer service, I would NEVER EVER recommend them to anyone. Because as soon as you deal with the customer service you hear different things all the time.

All the experience has been frustrating and mentally draining!

Shocking customer service. Code cannot be reimbursed, you don't get your money back.

They do not reply to emails, their system does not work half the time, it took five calls I st cancel a package. When I asked an employee to mail me some info he said I don't have time. A joke of a company.

Awful. Bought prepaid SIM in Germany and never worked. Went back to store 2x and guy was an idiot. Would not return our money even tho he knew it didn't work. We were in Tübingen. Buyer beware.

I was charged 225 euros at an international rate for calling a 1800 toll free international customer service line during which I was on hold for over an hour. I was completely unaware that they would charge for this because its 2020 and its unbelievable that a communications company would still charge for this. They refused to give me a one time dispensation over it either. Customer chat was very unhelpful in this matter. Go with a bigger carrier, its not worth the cheap rates when you get hit with a massive, unreasonable fine for something that has no business being charged for in modern times.
