Address not updated on all accounts, and still with the same banker who doesn't provide service

I have gone through the trouble of going into a branch to update my address, just to discover that despite my request to update all my accounts only my cheque account was updated. I contacted the FNB Private Client call centre to resolve the issue where I was told to go to my "Private Banker," and to my dismay learned is still Chadwin Tibbetts which have previously shined in his lack of service. As I have previously asked to be assigned a new banker, I requested to speak to the call centre agent's manager who in turn tried to get rid of me in classic FNB style by putting me on hold indefinitely. Nothing resolved, just more time wasted trying to get FNB to do what I'm paying them for.
