Account application such a pain

I app**** for an account online on the 10th April, I received an email saying my account has been provisionally approved and that I must send my 3 months bank statement and ID to activate my account, 72 hours later went by with no feedback nothing from ackermans accounts. I sent emails, called the call centre yet no one could help me with feedback about my application. Eventually, after emails and calls I got an SMS saying they only received one bank statement and that I should send the rest. Even though I attached all my documents to the email I resent anyone, till today the only response I'm getting is a mere, sorry for the delayed response, call centres response, sorry you must just wait because they did receive your documents, ackermans cashier, just wait for an SMS, there's nothing I can do from my side. It's so frustrating that I need to go through all this just so that my account can be activated. I'd hate to see the kind of service I'll be getting should they eventually process my documents. It's so disheartening.
