Bad Service/ Untrained staff. They gone to big and cant handle the work load

I am totally dissatisfied with your service. It's been one week and no one from your office has bothered to return my calls including the Manager. The Sandton office's phone when you call, you have to hold on forever. At one time I waited over 45mins. It's so frustrating having to call so many times from different departments and not one person can assist me. I called again today and was asked to send another email but to customer care. It's like nobody is taking me seriously. When I get through I am advised that they are unable to assist as Phuti is off work and they refuse to transfer me to the manager. The agreement was that I hire the vehicle for a month. I paid rental in full for the month and was told by Phuti at your Sandton branch that I could use the same agreement in CT. I later found out that the contract had ended and a new contract was loaded for CT. I did not agree to this! I called Phuti 3 times to confirm with him that there will NOT be any additional charges. You can listen to your recordings. On my return to JHB at OR Tambo the lady that assisted me told me that a new contact was open in CT and I have to pay more if I want to continue with the rental. If he had informed me the contract would have ended. I would have kept the vehicle and just urbered in CT.
