peoblem with my calling and internet

Did you put your customer number in the transfer reference and transfer the payment to the correct account (as shown in the invoice)?

Hello ​@Nasser Alhthily ,
welcome to our o2 Community 😀
Unfortunately, we haven’t received your payment yet. 
Did you include the correct customer number in the payment reference? 
Kind regards,
Solveig 

I have paid the full outstanding amount, but accidentally forgot the Kundennummer in the Verwendungszweck. Please manually assign my payment to my customer account and release the blocK

It is not possible for the moderators here to assign it manually.
