Worst banking services

Its been 2 weeks that I've been trying to open an account with discovery bank on the app but every time they cancel the application and tell me that I didnt send the right documents. This is funny because I go to FNB and open a new account with the same documents. Can't understand how discovery bank is willing to loos client. They do have a limited amount of employees that really want to help but as soon as you want a call from the department that deals with what documents are accepted you will hear nothing from them.
