No way to treat your loyal customers FNB

I have been a happy customer with FNB for some years now but it's the second time now that it feels as if I were always just a number to them. The first time was when I tried to apply for a home loan but they had no interest in even trying to assist me. Now the second time is when I try to apply for a personal loan and they want to ask me 22% interest. Could this be right? I made it clear to the consultant at the bank that I am not happy and he logged a complaint with FNB (FNB:-) Ref ********** ) and stated that I will be contacted within 2 hours. It's been days now and no one has contacted me yet. Why can they not look after me as a customer by giving me a much better interest rate. I am earning a decent salary and have always been a loyal payer when it comes to payments of credit card det ect. Even my interest rate om my credit card is a joke. I started years ago on 18% and was told that they will relook my rate when I sustain a good credit record. For the years I have been with FNB they only brought it down by 0.4%. Still more than 17%. Is this really the way FNB looks after their customers? The worst of it all is that every time I had an issue with getting a loan I went to Standard Bank and they were always happy to assist me and I don't even bank with them! They gave me an awesome interest rate with great service without even begging them to look after my pocket. I sadly had to go to Standard Bank again to apply for my loan and by the looks of it they will accommodate me ones again. I am deeply disappointed and seems to me I need to take my entire business to Standard Bank.
