Proximus Reviews 

The most horrendous customer service of any company I have dealt with. Takes forever, and doesn’t give clear answers. Instead of trying to find solutions and work with a customer it’s completely one sided, lazy employees.

contant loss of image and connection on pickx. so called no wifi connection. 130 permonrh. luckily i have a DIGI back up on tablet.PROXIMUS ANSOLUTELY RUBISH ...NO WORLD CUP FINAL because of this

Anyone considering proximus - just do not.
Worst value for money:
-no service at all (i couldnt possibly call that shit show a service)
-average quality of products
-very unethical marketing techniques

They abuse the monopoly status

Extremely rude customer care service and rude support team. They are sheer disappointment and extremely rude staff

Shocking not sure if these where originally called Heatzen this is the name they used when they recently rang Heatzen is who originally installed our boiler but they installed a boiler to big for the cupboard blamed me saying I asked for the boiler but im not the engineer if it doesn’t fit then they should have said it couldn’t be installed now they want me to cut out my cupboards plinth so it would be able to be serviced. I said no and they left it there saying they would come back to me but they have vanished off my WhatsApp, getting on 2yrs the manufacture said they have put on the system that tge warranty with them is void and I took a payment plan out with British Gas and they put warnings on it so who is bringing these people to account for what they do to people it’s a disgrace. Maybe I should get the boiler replaced snd tgen gp through small claims and they do the government grant ones do maybe if anyone knows someone in the DWP who pay these cowboys ask them to take them off the list, there should be some system to make sure these people don't keep ripping people off but they should never be able to claim the grant money or anyone’s money until customers are happy.

On 30 May in Huldenberg. We celebrate the Proximus no Internet we don’t care day! We are without internet since yesterday morning. Have called 5 times and never the same answer. Nothing has been solved 24 hours later and they don’t care at all. How are we supposed to work? We need Internet for our business and we loose money every hours without a connection. Our neighbours who have Telenet have no issues. It is much faster to switch to Telenet than to wait for Proximus repair. I am preparing a case.

a very bad supplier. I do not recommend it

I pay 40 euros per month for extremely slow internet. It takes me 30 minutes or longer to download something as light as 8 gigabytes. Proximus is ran by scammers who want your every last penny for below average internet speed.
I've been using Proximus since I moved to Belgium, thus 2019, however I never realised that this is genuinely the worst option out there in the whole country. A homeless man down the street would be a better internet supplier.

Timewasters. I wanted to repay my phone early and cancel my subscription, and than I was manipulated by their staff if I take home Internet I will get huge bonus.
During conversation prices were changing always up, but still agreed at the end.
Anyway when it came to activation I realised they put cap 6TB on my home Internet. Ridiculous when woman on the chat said it is going to be unlimited! They lied.
Now I just cancelled my home Internet and mobile, of course I'm going to pay residual value of my phone but I will never again step in something connected to proximus. Liars.
For proof I do have screenshot but unfortunately I can't upload them here.
stay away.

Edit: and on top of that I'd like to add these people are greedy, they knew I had traffic accident and can't move with my feet broken, still wanted to trick me. This says everything about them.

I was customer of Proximus for more than 10 years. Based in my experience I can confidently write that Proximus as a service provider, specially customer support (also same mentioned by other people they are difficult to reach) is almost hell . They don't care care if customer asks for some clarification and silently ignore all your mails. Because of this I was forced to pay more than 156.xx euros for extra 2 GB accidentally usage of data.I do understand I execeed the data usage by 2 GB (I had 40GB in package) just because some upgrade took a lots of it but still 2GB over 40 GB standard package is not that much and it can happen once or two time in 10 years but they don't care and even they don't reply that is really annoying.But one thing they are very good at to ask for bill payment repeatedly and adding 10 euros for each dealy. They don't forget this but they just forget this customer sent us multiple mails for same topic for clarification. But trust me this extra money you recover (156 € for 2Gb extra data) won't help you to compete in market. I would improve customer experience if I were in position to do that and also I will support old customers for such accidental usage as loyalty. It is not late... please rethink!

The fiber is finally on my street. Tried to book an appointment for installation via their app. No way. Called them. Appointment fixed. The foreseen day no one came. No info received, no cancellation message. Called again the day after. The lady on the phone didn't know why the technician didn't come. She said she will investigate and come back to me same day. Nothing. Called again the next day. Arranged for another appointment. From 8 to 17h.The appointment day till 16h,nothing happens. The second time. i wouldn't expect someone to come after 16h without letting me know. So I called them again. The same answer as before. Don't know why, investigation, letting me know. Nothing happens. The next day finally I received a text saying that the appointment of the previous day was postponed!!!!! I could use the link they send to fix another appointment. And of course the link worked but no way to change the expired appointment there. I will call them again when I will be strong enough mentally to support their incompetence.. Apparently no one gives a dime in proximus having such a low score. They have the monopoly of fiber on some areas and they don't care. Just increasing the prices that are already on the highest in Europe.. I'm thinking of starlink instead.. Catastrophic proximus.. They should have used Distalis or Nihilcuris as name instead of proximus. Or is that proximus just to our pockets???

I had a stable downstream speed of 90–92 Mbps for three years.
On March 20th, 2026, the line started dropping, so I contacted support to check the issue. Since their intervention, the disconnections have stopped, but my maximum speed has dropped to only 55 Mbps.
Even the technician told me I should “be happy with what I have”.
Seriously? I had 90 Mbps for three years, and now I’m supposed to accept 55 Mbps as normal?
It’s like buying a car, doing all the required maintenance, and afterwards being told:
“Now it only drives 90 km/h on the highway instead of 120 km/h — just be happy with it.”
I’ve never experienced service this poor.

There was a huge outage, they provided no communication. Proximus needs to send a simple text, we are having network issues.......

Worst customer service. You cannot charge premium and have such service. They need to improve it asap.

What an agent ??? is this really how proximus treat customers ?i can say alot but in summary Untrained agent, disrespectful and only shouting without doing his job efficiently . does not worth even 1 star

Absolute efficiency and friendliness of the Proximus agent. Mohamed of the Proximus shop in Rue des Tongres, has been fantastic in working even a very early Sunday, yes Sunday, in order that everything was functional before my trip abroad on Sunday. Thank you Mohamed for your excellent service.

Opacity by design.

Whenever I contact the support, they tell me a different thing and when I ask to have something in written they say it's not needed.

Their application shows ongoing requests, and it's opaque as it can be. No summary of the discussion, or global understanding.

Last experience: They cancelled a request for service based on the "no" from a syndic, which has no link to our house. They won't reopen it or explain anything, and trying to get explanation result in having tickets closed with no information.

I was without internet for a whole week due to a line fault, and they still haven't sent a technician. Their phone support keeps promising a callback that never happens. Absolutely pathetic customer service for such a big company.

Worst customer service ever!!
