Disappointed and poor service

Im extremly dissapointed in your service.. Im a titanium card holder and pay alot of money monthly to get the best services, that include being assigned to a personal banker. My 1st banker was the best banker which left your employment (Soso).. Than I got the second personal banker which was not what your advertise "available 24/7", I requested to get a new banker as I was not happy with her services and when I require assistance within business hours, i don't get feedback, I have to follow up after 2 days with emails. I requested for a new personal banker that will assist whenever I need as I'm paying a hell of alot of money to get the best service.. She also left and now I have another new banker which is exactly the same as the previous one, I don't get feedback when I sent emails or request assistance during working hours, I have to go into the bank to get which I fail to understand what is the point of paying these money's and having a personal banker that do not care about their clients. I've been a client for over 9years and all my products is with you, business account which I make over R2mil per year and that banker I also want to change, credit card, cheque account that,etc.. I even convinced my wife to bank with you but it seems that was a big mistake as it seems like her banker is available when needed and she have all his details yet I don't even have mine and until less than a month ago I was advised who my new banker is which is already of poor service. When you have top clients that pay alot of money for a personal/business banker the least the personal banker can do is respond and advice they will get back to the customer before end of business or ensure that their out of office is switched on cause it's these things that make a loyal client go to a different bank that live up to their standards. I want to request a new personal and business banker asap.
