Appalled at service

I app**** for a nedbank credit card online on 14 July 2019. I have done constant follow ups on my side as no consultant has ever been in touch. I have since received two smses one stating the application is been processed , the second one indicating that the application was provisionally approved and awaiting 3 mths bank statements of 3 mths payslips. I have send through these documents along with a copy of my ID on three different occasions. I have spoken to at least 6 different consultants over the past week advising that the application is in the verification process. This morning I called again following up and I'm told the agent made notes on the system that they cannot any a hold of me, the payslips do not correlate with the letterhead whatever that means and that they have been trying to get a hold off me on which number I do not know. When the application was done I submitted all my current contact details and employer details. I have had an account with nedbank five years ago and it seems the agent is still using these outdated details. Can someone please sort this out.
