I am taking my old number from another service provider to O2. Cancellation with the previous provider is already processed. And my new sim(ordered online) was delivered by post with a new number. I have activated this new sim card, cancelled the contract with the previous service provider and now I am stuck with new number, while I request for porting long ago. Many times, I called the customer hotline, their response is only in German and don’t even bother wait for my response and cut the call. Someone please help me to port my old number.
