Hi @Kamil B,
nice that you contacted us again here in our English community.
Great that you already extended one of your contracts for further 24 months. We appreciate this very much.
I regret that you like to cancel your 2 other contracts now. May I ask you for the reason of ending these contracts. If you like to receive a nice offer, just let me know.
If you like to end these contracts, please follow the instructions in this link: http://g.o2.de/cancelation
You also have the possibility to send us a cancellation letter. Just fill out this cancellation form: cancellation letter
If you still like to change the ownership for one of your contracts, please do this online under this link: http://g.o2.de/inhaberwechsel
I hope I could be of help to you.
Loving greetings,
Tobias
