RMB Lack of interest to client and Don't care att.

I changed my primary bank about a year ago after not being able to get hold of my private banker, even after messages was left for her, eMails was send as well as SMS's send to her cell number. <br> That being said, I've call the service desk last year, to change my cost structure from unlimited to standard, that could save me about R209 pm. When I followed up why that was not done after a couple of months in January, the service desk acknowledge they had record of that conversation and would rectify the incident.<br> Today, for the third time, I followed up why I'm still paying the higher amount and why this still was not rectified, I was told I requested the unlimited option on 11 March. This is insane because I haven't even spoken to the bank at that time.<br> What do I do to get hold of my banker or just to believe what the person on the other end of the line tell me he is doing.<br> The service desk agent informed me that the assistant to my private banker will contact me today to rectify the situation, but as expected and from experience, this did not happen.<br> To whom can a private citizen turn to assist, if a premium bank can't deliver on a simple straight forward request?
