Bidvest Bank - Ba Service + Processes

Trying to get service on a business bank account. I am given a number of a so called private banker, but the number is unavailable for extended periods even when the call center tries to put me through.

To be told that the said private banker is the only person who can assist with a straightforward thing such as limits is ridiculous. You would expect if a person is unavailable, there should be alternatives in terms of where one can get service.
