Bad customer service!!!!!!!

I app**** for a American Express Credit Card more than a week back through clearscore, ever since I app**** I've been receiving sms's to send proof of income, payslip or bank statement I've been sending those documents for over a week or without any finalization from Nedbank, last week I received a call that my first name was captured as my second name, that I needed to send my Id copy and proof of income, and I did, days later a sms comes through "please send through proof of income" again I did, again today same sms, I then called their call centre, the lady could not assist as she says the system is not offering her any information and that I should wait, wait for what exactly,,? for another sms telling me I should send through my document again?
