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.

Thank you very much for your support. I look forward to your confirmation.

Kind regards,
Sanjay Sardiwal

Don't post your phone number or other personal details in a public forum!

You should receive I formation by email. You can also call customer services to check the status.

    Hello ​@sanjaysardiwal33 ,

    It's unfortunate to hear that such an error occurred during the contract renewal.
    I just checked, and I don't see any cancellation of the contract renewal here.
    We cannot process the cancellation here, as the renewal was carried out via a reseller.
    Please contact MediaMarkt today to clarify the matter.

    Just a quick note: please do not post any personal data/phone numbers here, as we are a global public forum. 
    I have therefore anonymized the phone numbers.

    Best regards,
    Maria

      Hello ​@sanjaysardiwal33 

      You haven't responded here yet. I replied to your other post today.
      The conversation continues there.
      Please always post your concerns in a single post, not in several. This makes it confusing for us and other users.

      Best regards
      Maria

      Hello ​@o2_Maria 

       

      The guy from Mediamarkt told me that he would talk to his boss and see what can be done further. I’m not sure how long will this process take.

       

      Best Regards

        Hello ​@o2_Rebecca,

        I didn’t receive any confirmation yet and it’s not updated as well in my O2 app. Do you think it will take some more time for the confirmation? Thanks.

         

        Best Regards

        Hi ​@o2_Rebecca,

        I just spoke to one of your colleagues over the service chat. They tell me that the  contract is not cancelled. But however you have stated above that the cancellation of the contract was recently completed.

        Please can you let me know who is right here? So that I can proceed with the next steps in case the contract is not cancelled. Thanks.

        Best Regards,

        Sanjay Sardiwal

        Hallo ​@sanjaysardiwal33 ,
        I'm sorry you're having so much trouble.
        The shop received a follow-up inquiry from colleagues regarding the cancellation.
        He has not yet responded to this.
        That's why nothing else has happened here.
        Please contact the shop again. 
        Kind regards, Solveig
