Bad customer relations

My account was suspended with out notification. Phoned customer care they say the courier guys suspected that my Identity was tempered,I mean who is he to say that is he qualified to say that did he do a crash course at home affairs. I was at my house when he delivered my card if he was not sure of my Identity I have a valid south African passport and drivers licence or we could have gone to the police station to verify my identity I live near a police station. So they suspended my account based on that and never bothered to phone me to resolve this it has been almost 2 weeks now. I have sent numerous emails to the ***** division no response and they don't take calls. I just need my money I have escalated this but no one has come the the party. At a point of just wanting my money closing the account and move my business to a bank which cares about my business
