Not user friendly – DB Navigator Review

Not very user friendly!!! Credit card on file for over a year and suddenly won't work! DB says it's our card...Chase visa says my account is OK!! Trying to change card thru the App but there is no place to do it! Calling is problematic as no service phone # seems to work & there's a charge of at least 20€ cents per minute to get help!!!! Oh...and not all pages have English translations!
