DKB bank speaks German only.
I sent them an inquiry in English via Messenger and they replied they require German language because they conduct all business in German.
I do not speak German and if the bank refuses any communication in English, it means I will not be able to do business with them.
I bet they issue all papers, documents, contracts, account statements in German. I would like to know what I sign.
I'll wait and see what happens here in October after mBank says goodbye to Miles & More.
No pressure, as long as I keep my SEN status.
