Dear o2 Customer Support Team,I am writing regarding an issue with a mobile contract extension that was processed incorrectly today at a MediaMarkt store.I visited MediaMarkt today to extend my mobile phone contract for my correct phone number 017xxxxx. Unfortunately, the employee mistakenly applied the contract extension to a different phone number, 017xxxxx which is also under my name.After the mistake was identified, the MediaMarkt employee immediately raised a support ticket (Ticket No. 2xxxxx5) and informed me that the incorrectly applied contract extension had been cancelled.Please can you let me know  that the contract extension for the incorrect number 017xxxxx has been successfully cancelled and that no charges or contractual obligations will arise for me as a result of this error. if not please can you tell me what would be the next steps that I would need to follow this mistake

Hi O2 Support team,2 years ago I have relocated to different city. The DSL line was moved, thanks to the DSL line I have the Kombi option on my 2 other contracts - at least in theory.two years ago was deleted the Kombi from one of my mobile contract - and noone knows why. Youi have helped me here by putting some 2 years discount on my contract which was the same amount as the kombi.unfortunatelly it is gone after 2 years.Can you fix the Kombi option for the phone number with ends with 48 ? (best would be to reactivate the kombi again so I do not need to come here with the same problem again.)the other mobile contract have no such problems. Thank you

Hello,I’m new in Germany so my dad got me an O2 number I saw an extra charge of 7.99 for “added services”  but I haven’t subscribed to anything. I later found out it was for Qello music streaming. I didn’t even know what that was 1 hour ago. The deduction has been going on for two months and I don’t even have the Qello app on my phone. I have been able to cancel it but how do I get a refund ?Thank you.

Hello O2 Team,​I have been an O2 customer since Jan 2020 (Mobile) and Nov 2022 (Home Internet). I am currently paying €24 for my Mobile M Boost plan.​I want to switch to the Unlimited on Demand plan for the €19.99 Kombi-Vorteil price. It is very important that my existing free Multicards from my current Boost plan remain free (€0.00).​Although my contract technically runs until 2027, I would like to move to this modern offer now given the upcoming 2026 price changes. Could a moderator please send me a personalized offer for this via email?​Thank you!

I transferred money to pay bills and missed customer number since 4 months ago, it seems my money did not reach to O2. Last week, I was blocked outgoing calls, I called to billing departments and they can not speak english, Thus I sent an email to Impressum and did not receive any further updates. What should I do next?The monthly bills has been deducted, do the bills need to be paid full amount to continue network?Ps.1 all bills had been paid.Edit o2_Kathi 09.02.26 Moved from the section o2 Mobilfunk to English o2 Community

Hi, I hope i may get clear answer from here. It is my first time to experience today that I cannot connect other devices. I usually use everyday my O2 sim as hotspot for my printer, other phone and laptop. Is it possible that O2 automatically blocked this feature? I pay 29,99 per month for unlimited internet so I don't see any problem about it because I routinely hotspot device since I got this sim. Or is there an error for today? Enlighten me please. Thanks!

First of all, I would like to say that I am very disappointed with O2 service. This is the worst customer service I have ever experienced.I have complained several times since October about my contract and my bill, as O2 made a mistake. I have called several times and filled out a cancellation form multiple times.I cancelled my phone and number contract on early September 2025, but somehow only the phone contract was cancelled and the number contract not. So I have 2 phone numbers now. I tried to call the customer service, and they said I had to send a written letter. I did that in October, but no answer until now. I called again and again, but still no answer and no solution. I called again last week, and they told me to fill a Sonderkündigungsform online. I did that, only to get a letter from O2 saying that they need my phone number. This does not make sense at all as I did everything online and O2 has my data!This week have filled again the for

I have to start off by saying my German is not good enough to have this conversation with the service team and it's so frustrating. I paid my bill since January only for my invoice to read that I have outstanding. I tried to call and luckily I was put on with someone who understood English, we were able to identify that the reason is that I did not put the customer number on the payment - I had forgotten. But I was able to identify what reference I used. Unfortunately we could not do anything about it that day because they were having issues with their database. The guy said I should call back on Friday and I did but unfortunately he wasn't the one and the lady who answered did not speak English. Now a month later my internet is cut off because of outstanding balance that i have already cleared. There is no email to contact, what can I do? I can not even call customer service  because no service to my phone. I work from home but I can not work because my internet is cut off too. It'

I got scammed by this guy who was at O2 shop Am Harras. First of all he was extremely disrespectful towards me for no reason. I went to the shop in January to get my contract extended, I was enquiring about different offers, the guy was not cordial at all to inform what offers are cost effective. Anyhow, I got my contract extended and he asked me to sign the contract. While I was about to leave he told me that you get this free sim card. I didnt need it but he asked to keep it and I just put it in my bag. Today When I checked my invoice I was charged 73 euros. When I called customer care to enquire about why I was charged so much, I got to know that there are two contracts active on my profile. I had no idea about it. WHEN I WENT TO SHOP I WAS TOLD THAT YOUR CONTRACT IS EXTENDED AND WAS NOT INFORMED THAT HE IS MAKING ANOTHER CONTRACT IN MY NAME. THIS IS A FRAUD, I REQUEST TO IMMEDIATELY CANCEL MY SECOND CONTRACT AND REFUND MY MONEY.I have a feeling this guy did it INTE

I got completely scammed by the O2 store at Muncher Freiheit and it is totally unacceptable and I want a refund and if possible cancellation of my contract.As a student who was trying to find a affordable sim card provided and I thought O2 would be a nice one. I went to this store in Muncher Freiheit and the guy there told me that this package (O2 Mobile M) is 20 euros per month and HE DID NOT MENTION ANY FIRST TIME OPENING FEES!!! He also gave me another sim card which he said it comes with the original one (O2 Mobile M) for free although I never asked for it. I just checked my mailbox to see that my first month fee is 80 euros!!! 4 times more than what I expected. The only reason I bought this sim card was the fact that it was 20 euros per month now I have to pay 80 euros. It shows 40 euros for the second sim card that I never asked for too. It is nothing but scam to tell me it is 20 euros and charge me 80 euros after making me sign things really fast.

Hello O2 team. I tried to move my phone number to Vodaphone, but it was not possible.I’ve liberated the number for 30 days. But Vodaphone replied that I only have 3 months after my contract with O2 ended, to process the portability to another company.Can you confirm if that information is correct, please?. Thank you very much.Edit o2_Kathi 09.02.26 Moved from the section o2 Mobilfunk to English o2 Community
