Cannot update the telephone No. for online-banking
Hallo! I want to open the online banking service so that I checked to to process it on the BW website. When I tried to complete my data, the telephone, I found I cannot submit the info. I tried several times and failed. Could you please advice how to continue? Besides, how can I get the TAN generator? Should I apply it online? Thanks a lot. Best regards, Pengchao
