Hello,
I am going to leave Germany at the end of April. I want to terminate both of them. I have the following contracts with O2.
1. Contract for my Handy: O2 Blue All-in M (Kundennummer XXXXXX)
2. Contract for my O2 DSL M (Kundennummer XXXXX)
Please suggest me whom I can contact in this regard. Do I need a deregistration certificate from auslandbehörde?
with regards,
XXXX
XXXXX
