I have recently bought an O2 DSL connection and received my first invoice. When I initially ordered the connection I did not have a German bank account, so I put in my danish information. However, now I have a German bank account and would like to use this account to pay my bills. However, when I try to change the account online I have two problems:
- It only allows be to change the BAN not the BIC nr.
- It gives me an error if I try to change the BAN nr.
Can you please guide me how to change my billing information? I prefer if this is possible to do without having to call the hotline, as I usually find it very difficult to get through to someone that speaks English (my fault cuz I barely speak German :D).
Any help is appreciated!
