Private banking preferential rates my ass

So in December I was recruited to join ABSA private banking,I agreed because it sounded better that I will get preferential rates when it comes to facilities, well at least that's what I was told,now I realise it was all a money making ****,first and foremost, they refused to refinance my cars that I bought while I was still with retail banking,two cars approved at 15% and 13% respectively,well I thought it better to have them than being declined,yesterday I decided to trade in one of the vehicles,I thought maybe I will get those preferential rates but neh it was a lie,I got approved indeed but at 14,5% rates,what the hell? I told them to keep their offer,now I think I will leave them for good,they're in it for money,my credit score is good and all that but now I see them for who they are,I just need to sort a few stuff I have with them and its bye bye,anyone who falls for this private banking nonsense from them,they're on their own
