FNB does it again

So FNB does it again..... after being a loyal client for over 30 year. I am once again amazed at the disregards FNB have for their clients. I am a FNB Private client and reviewed my credit card interest rate, as a private client I pay 22% interest on my credit card. My wife has just been upgraded to a ABSA private client and get the amazing interest rate of 11% per annum. When I called FNB they about the fact they are charging me nearly double of what I could get at ABSA. They offered to review it. Finally a few days later I received their reply. \After an interest rate review
