All stories never actual work done

So i get a pre agreement with FNB Credit Limit Increase and i accept then i get another sms saying it is declined due to afforability, Help me understand previous salaries is R10891 my new salary is R24950.00 and i get declined. Bare in mind i accepted a Quotation of R25000 increase in my credit card. I then give a HEllopeter complaint and then all of a sudden people wake up and phone me and guess what now its quiet, I then re apply with my new salary *12 and i get a quotation i accept send through signed quotation and payslip and guess what still nothing i then also increase my overdraft and guess what still nothing

I want this sorted otherwise i go to CPA because ive accepted a quote
