Worst experience trying to get a credit card at FNB!

I tried to apply for a credit card on FNB online and got declined because I was a new customer I was asked to send 3 months bank statements or 3 months payslips to them which I did on the 27 of June. I got absolutely no call back from anyone regarding my credit card so I phoned and they told me to resend the documents and I did, I get no response from them so I call again and they tell me they need a paid up letter from an account with them I closed more than a year ago which I did send and no response from anyone I call again they tell me my one statement doesn't show salary for one month even though they have 3 payslips and 3 statements from me and they only require payslips which I found out later when I called again to follow up they told me they have everything they need to continue. I wait a few days once again no call from anyone I phone them nothing was being done my application has not even started yet. I get told they see my problem they will send an escalation for my application to be done. I wait a few days and no call from anyone I call again nothing has been done. I get told sorry for the inconvenience they will send another escalation and tell me to wait for a few days and to call them back. Today is the 14th of July I phoned them and still, nothing has been done regarding my application and they told me they will escalate to a manager I don't know what is going on I have phoned a lot more than I should have and not once have a received a call from anyone regarding my credit card application.
