FNB Business Banking Dissapointment

We have a Gold Business Account with FNB for the last 18 months, to say the service we have received is poor is an understatement. We have tried to reach out to our " Business Banker" to get assistance for many issues to no success, branch visits are no help. The promises made by FNB Business Banking are all false, not sure if its because we are small business? We at the point of closing our account and moving elsewhere because the lack of support is affecting our growth.
