I cancelled my contract (Mobile and Dsl) at the O2 store today (16th Jan 2020).
Reason - I am moving out of Germany and going back to my home country. (Abmeldung end date of registration is 21st Jan 2020)
They cancelled the contract in their system, made me sign a letter and gave me a document called Übertragungsprotokoll. They told me to wait for a week to get a letter from O2 for the final confirmation of the cancellation.
Please let me know the next steps in the process.
> Till what date can I use the mobile and wifi?
> Are there any further cancellation charges?
> When should I post the modem? - Is this free of charge or do I need to pay for sending the post (to a Telefonice address in Hamburg)
Your help is much appreciated.
