Damaged Car and failure to register the vehicle

As a first time car owner I must say dealing with Hyundai Bryanston has been my worst experience ever , first of all , when we bought the vehicle it took almost 2weeks for my banker to get the tax invoice , and stories were made up about the sales person not being available. after collecting the vehicle 3 weeks ago , the snag lists which were raised regarding the vehicle has still not been fixed , to make matters worse the vehicle has still not been registered, I have been doing a follow up with the manager Sanet , who has now told me , the sales person who was handling the deal resigned and someone else is handling the deal , she referred me to a guy called Warwick who in turn has not responded to me emails nor returned my calls , this is the worst service ever , and taking into account the manager Sanet is aware of the issue and she is not doing anything about it. Hyundai Bryanston has the worst service ever .
