Standardbank Prestige no benefits

I am Prestige account holder and not happy with the service from the institution. I were blocked on the mobile app to accept an increase on my credit card due to FICA. The system allowed a portion of the amount. I went to the branch updated my details and the consultant advised that the same error she received and all will be in place and i can try the app. When i arrived at home the app gave me the same error. The IT dept advised there is a glitch and i had to to phone prestige banking i did that and a gentleman Lelileso advised me that he cannot apply for the increase online ..... why do i have a prestige account ? Had to wait for an hour on the phone before assistance and still to hear there is no one in afrikaans nor is there no one who can solve the problem. I hardly visit the bank or ask but when you do there is no one to help. The contact centre is there to assist .... why cant they help? I think i must move my business to another institution
