POOR service

I logged a secure message with Staff Banking centre to enquire when I will be credited interest on my account as I have over R300 000-00 credit balance. A day or 2 later a branch consultant phoned to advise me on Service fees. Service fees??? That was not my query. I advised her what my query was and that she needs to come back to me when she is better prepared with all the answers as she was making me hold on the phone forever. After not receiving a response after a day or 2 I logged a new query. I have STILL not received a response. I logged yet again another secure message. The 3rd one to date. I am not asking to send a man to the moon, I only want answers. Is it so hard? I really wish to have this issue resolved ASAP.
