Hi @siddd,

I regret that you like to end your contract. What is the reason for the cancellation? If you like, we can look for a good offer to prolong your contract. What do you think about it?

If you like to terminate your contract, you find here all information: http://g.o2.de/cancelation

Of course, you also can send the cancellation by fax or post to the following address:

fax to 01805/571 766

Telefónica Germany GmbH & Co. OHG

I look forward to your reply. 

Loving greetings,

Tobias
