Moved outside EU, have outstanding amount

Hi, my (postpaid) O2 contract expires soon and I have already left EU. But the bank account which was linked to my O2 account for SEPA direct debit purposes has already been deactivated. I have another EU account, but outside Germany, from which I have wired the amount which was due in my latest and final invoice. Just wondering if someone can check whether the amount I paid has been accepted. I have given my Kundennummer as the reference in the transfer. 

Thanks!
