Standard bank is not serious about service

I have an issue with one of my accounts with Standard bank. I have been trying to resolve it and have been sent from department to department, the one blaming the other and saying they cannot do anything.

Frustrated, I have tried to speak to Customer complaints. Once again, I was told they cannot assist me. I asked to be put through to a manager, and was put on hold for 53 minutes. Who do I complain to i customer complaints cannot even assist?
