ABSA Private Banking thinks clients are Dumb

I have been a FNB Premier client for the past 10 Years. I had recently booked an appoint with a private banker from ABSA to see if ABSA could offer me a better deal on my current products I have with FNB. I was told by the ABSA private banker that ABSA has better products and that they will definitely give be better/competitive interest rates. I have now done the switch over from FNB to ABSA private banking to find out that my interest rates are higher and my credit facilities on my credit card and overdraft are half of what I had with FNB. Only after I informed them I had changed my salary deposit to the ABSA account and I changed all my debit orders to my ABSA account they sent me an email saying sorry this is what the bank can offer me. I have tried several times to contact my private banker to speak to him over the phone with no luck. I phoned him 15 min ago and he gave the phone to his colleague who told me he is busy and will contact me later. I really don't know what to do because they are offering me **** interest rates and payroll is closed for December to change my salary deposit account. I am Disgusted with how I am treated and with the false information i received from ABSA. Who would want to change from having a 16 Percent interest rate on their personal loan to having a 20 percent interest rate.
