Hello Avila C Caines,

Thank you for reviewing us. I understand you are not that positive since you are still waiting to receive your money back from us. We always try to pay within 14 days so we are assuming something is wrong, in the sense that maybe we settled the amount with an outstanding amount.

I would be happy to check for you. Will you please respond to our information request?

Regards,

When everything runs its fine

When everything runs its fine. But when you need them, for example when their mobile app is fooling you, they are nowhere. Really awfull support. And their callback promiss they dont keep.

Update after response Oxxio;

If you give the option for a callback; call back. 7 attempts didnt work.

Horrible customer service, unfunctioning app

Although I applied with my own IBAN number to get a contract with Oxxio, they charged a different IBAN. After receiving a complaint from the IBAN holder I contacted them to own their mistake and correct the IBAN. They refused to accept their mistake and although they confirmed they changed the IBAN, it is still the same incorrect IBAN.

Dear Taee,

I’m really sorry to hear this happened. It definitely shouldn’t have occurred. I completely understand how frustrating this must be, especially since you’ve already tried to have it corrected several times.
I’d be happy to look into this personally to make sure the IBAN is updated correctly and everything is set right.

Once I’ve received a bit more information from you, I’ll get back to you within 3 working days.

Kind regards,

Oxxio are liars and thieves.

Oxxio has owed myself and my partner EUR500 for almost - 1 year, we have called them over 20 times, and emailed over 10 times.

Each time they give us a poor excuse such as “oh my colleague forgot to do this”
OR
“Yes by next week you’ll have the money”

They owe the money to us as they forgot to switch our contract, and we incurred additional costs with another company. Oxxio was found liable and needed to pay us back.

We have threatened them with lawyers ( even sent a legal letter) and still no effort to pay us back.

I suspect they’re banking on people not being able to afford the legal fees to sue them.

Either way, if you can , avoid this company at all costs, they’re con artists and thieves.

Not even worth a single star

Not even worth a single star. They overcharge and demanded I pay an extra €1,400 on top of regular monthly bills for an apartment that’s currently unoccupied. Their customer service deserves 0 stars. I recommend staying far away from this company. They’re simply resellers for Eneco with no energy production of their own.

The worst company and customer service ever

Had a fixed contract with them and after relocation they forget to move my energy contract to new home while I had inform them 2 month in advance😳.

2 years after my energy contract they charged me with over 1900 euros for end year annual bills based on their assumed wrong numbers, while I gave them correct numbers and they refused to fix it, hundreds of hours sending email with documents and calls over phone and no solution. The most stupid customer service ever. had to take lawyer to fix part of the bill through firm company.
Never trust them.

Stay far, far away from this company!

Stay far away from this company!! When you need them, they are not there. They charge you based on estimates. When you paid to much and you want your money back, because you did not used much energy, you cannot reach them. They just ignore you! Terrible! For email contact they take 4 weeks to give you an answer!! Not 1 or 2 day's, but 4 weeks!

I was a loyal customer of Oxxio for…

I was a loyal customer of Oxxio for many year. Recently I recognized that what they charge me for electricity is way above the market price. I calculate on their website how much should I pay as a new customer, and I got a price. I got an offer 48% less!
So this is the way they treat their existing customers: no email, notification that "Hey, you could get a better price".

All they was replying to my contact: Yeah, we can give it to you IF you ask it.

Well, no doubt I have choosen another supplier.

Oxxio, simple and terrible

This is going to be very simple:
Oxxio delivers Electricity, Gas and Internet. It all works. But they scam you wherever they can. I do not have proof of course, because it always seems coincidental but it becomes very clear if you are ever their client.

Experience:
1 - I asked for the Electricity+Gas+Internet package from oxxio only because this way i would get internet for 6 months for free. They then put me in an only E+G contract because they apparently work with KPN and KPN could not deliver internet to my house. Bummer.
I actually tried KPN. And guess what? It worked.
So basically they lied to get me into a worse contract. cant prove it of course.
2 - through their app you can write down your consumption every month and adjust the amount you pay. If you dont put it in every month they calculate it for you. Great! For june this year I was on vacation and my consumption was basically 0. they calculated? 1500kWh. thats more than I use in a year.
Great! can I prove it is deliberate? no...
3 - at the end of a year you get your year-bill. for my year bill they had to return 35% of the money they took through the monthly payments made. Since I paid too much (35%!!) you'd think they would reduce the monthly payments.... they increased them by 10%.
4 - you can adjust the monthly payments in the app. you put in a new number that is >50€ and click "adjust". it then says: oh sorry there was an error... i have tried this multiple times, over a time span of half a year. same result. convenient.

i am now leaving the netherlands. so this is a full review now. they deliver, they give back your money, they dont break the law. but they sure treat you worse than i have ever been treated by as a customer.

Fraudulent company

I don't understand how this scamming fraudulent company still exist and get away with it. They claimed that their internet service is provided by kpn. I called Kpn they said that is not true. Their customer service is the worst. This company need to be sued for fraud and scam.
