2 months on and am still waiting for a credit card

I app**** for a credit card a couple of months ago through FNB and i have been calling them since.surprisingly everytime I call for feedback on the progress of my application I get told that there's a document missing that I need to send before they can escalate my application,this has gone on to the point where i had to send a new month's payslip because the earlier one was now out of date.Today I called and was told my documents are being escalated.this cycle has gone on for too long now and I demand an answer asap.your credit card service is terrible and non efficient,am sure there's no quality assurance over there.
