Premier Credit Card Limit Increase

I was convinced by FNB to move Premier as I would have dedicated premier bankers to assist me easily and on the app and this has not been the case. Firstly I called in and was told I can apply on the App. I did that and immediately was declined I called the call center again and was told the app does that sometimes and they will process for me there . They said all was well and asked me to send my payslips and passport number again which I did..... No response again for a few days and no follow up I followed up they said oh sorry its because they need the Reserve Bank declaration documents work contracts etc... which by the way FNB has on the system because when i initially app**** fnb Forex department did it for Credit card division! I resent that regardless and I was told in 48hrs all is fine and will be done.Again no feedback and I followed up on Monday and I was told everything is fine with the limit increase and it will be finalized by Tuesday and they will call me . Again no follow up or feedback then I called again yesterday 15 Nov because i got an sms in the on Tuesday saying its been declined then call centre now says sorry its been declined on affordability after all this process and making me fill and send this documents why was it not declined when I first sent the payslips last wee****?? Secondly I am querying affordability and you can see on my work contract and my payslips which I believe no one really checked that is impossible that i cant get an increase in limit I can afford easily a new installment purely based on my salaries and benefits and any other debt obligations I have. Please may this be rechecked and re vetted. I have told the lady in the call center she says its affordability and the tune changed after I had submitted please my this be looked into rectified with haste , I am dissapointed at being a "premier" client but the service , feedback and action has certainly been nowhere near Premier.
