Extremely poor service

I paid up my car almost two months ago. I have been trying to get the NATIS and paid up documents. I have left messages for Tumi Tshabalala, responsible for my account, but she didn't reply. I managed to get hold of her, after going through 5 other people. She put me back to customer services who wanted to put me back to her. I still don't have my documents. Their managers are in meetings. No messages taken. I must them back. What pathetic service
