N26 refused to update my name in the account when one letter changed. They requested documentation my country cannot issue, and just sending them two passports, old and new wasn't enough. That took them more than a month to figure. More than a month of a constant email ping-pong where they were requesting more and more documents, some of them multiple times over and over.
