Business not good enough

I have been a customer of FNB for quite some time, with a Premier Account and a Business account, costing me close to R1200 a month in bank charges... i have never had an issue with paying the charges, but now that i was successfully approved for an FNB premier credit card, it seems like my business is not good enough. I was approved on Tuesday, the account was added to my online banking, got confirmation that a courier will phone me, everything...yesterday i decided to follow up in fourways branch, only to be notified that my payslips need to be updated...no problem and i arranged latest payslips...submitted and everything...now today, after spending close to R200 in airtime, holding on for the call centre, i get transferred 3 times, still cant speak to anyone, and i just get told sorry we cannot phone you back if the line cuts...now i was also informed by validations department that due to a salary discrepancy, i have been rescored and approved so the process will have to start again....why am i still with this bank i dont know...
