O2 is charging me extra... again

Hello, I signed an o2 sim contract renewal of 12,99 euros per month and i am being charged 13.72 Euros per month. please what can be done about this?? I am not happy about this.

When exactly did you extend your contract? It could still be partially cancelled.

i extended my 02 sim contract on 12/03/26

And what does page 2 of the invoice say? It lists everything that is being charged for and what it's for.

29,99 Monthly and -17,00 Rabatt/offer = 12,99 euro per month.

And what is the €0.73 charge for?

Okay i made a mistake with the figures, the figure i earlier quoted was the figure in my contract that i signed, the figure in my current Invoice is Grundgebühren 31,28 euros - Vergünstigungen / Guthaben 17,56 euros = 13,72 euros .

Then it was calculated proportionally, the next invoice will be correct.

Hello ​@Kendocity,

nice to hear from you again 🙂 I know higher bills aren’t great, so it’s good that Bumer was able to help you out. It’s just a prorated charge in this case, and it should appear correctly on your next bill.

If you have any further questions, feel free to reach out anytime 🙂

Best regards

Hello, i just got the second receipt of the renewed sim contract and it has 13,44 Euros as the charge for last month, how do you guys explain this again bearing in mind that what i signed in my renewed sim contract was 12.99 per month??

Hello ​@Kendocity,

thanks for checking in again. Have you had a closer look at your bill yet?

On page 2 of the bill, you’ll find the charges that were billed outside your flat rate. As agreed, the base fee is €12.99. If you’d like, feel free to take another look there – the breakdown usually becomes clear right away 🙂

Best regards
Daniela

Hello guys, i am here again😥, unfortunately i am the architect of my current woes, i felt the 55GB i had for the initial two years contract was too much for me(mostly used about 34GB per month) so when it expired i downgraded to 30GB per month on the new two years contract and now my data finishes before the due date and i still have up to 4 days before the new month cycle, how do i remedy this situation, since i signed this new contract i have been painstakingly checking my data usage which i wasn’t doing previously , Can anything be done to this new contract?? Can i upgrade the data volume without paying double??

Hello ​@Kendocity,

that reads like missing about 4-5 GB each month.

With your mobile plan it will be raised by 5 GB after 12 months, the question is how to raise it until then. Our Speed Optionen are a possibility to raise your data volume without paying double, you can order them via your customer account. 

Best Regards,

Hey Guys, it’s me again, i got a call from the O2 customer care team today and was offered a contract of 15 Euro for 50GB data over the phone which i accepted, But it looks like this is a fresh deal and a fresh Sim Card will be sent to me because i was thinking it will automatically override the Old contract i had but this didn’t happen, Pls what am i missing, I was warned earlier not to accept any sim contract over the phone but this my 30GB monthly limited data issue drove me to accepting this new offer, I have tried to see if i can port my number to this new contract offer but i am told to contact the customer care, Pls what do i do now?? I need help.

Hello ​@Kendocity ,
please cancel the new contract. You received the relevant documents yesterday. 
A ‘Widerrufsbelehrung’ is included here.
Please complete this and send it to the email address provided. 
The contract will then be cancelled.
You’ll be able to renew your current contract again from 11 August 2026. 
Until then, feel free to check online or in the My o2 App to see which data options you can add to your contract. 
Perhaps the o2 My Data Unlimited Pack or a speed option? 
Kind regards, 
Solveig 

Many Thanks for your response ​@o2_Solveig , i have done as you said, I don’t understand what you mean by i can renew my current contract again from 11 August 2026, I just renewed this 30GB Sim contract in April 2026 after the first two years which was 50GB, is there a clause in the contract that i can renew the contract from 11 August 2026 before the actual termination notice date in March 2028?? 

Hello ​@Kendocity ,
Ii’s great that the cancellation went through. 
The phone number, you’re registered with here, was renewed in March 2026.
If you wish, it could be renewed again for a further 24 months from 11 August.
But of course, you don’t have to 
Kind regards, 
Solveig
