Hi dslinternet,

I'm really sorry that it doesn't work. If the owner of the bank account stays the same, I can change the bank account data for you. In this case please send me a private message with your customer number your customer password and the new bank data.

If the bank account owner changes, we need a signed SEPA madatory with this form.

BR,

Dany
