A revolting experience from VW Menlyn for a pre-owned BMW 1 series purchased.

I purchased a BMW 1 series from the VW in Menlyn. Disgusting service received from Suzette van Niekerk and empty promises from her manager Bennie Welgemoed. I was called several times to come and collect the vehicle only to find it faulty with every attempt of collecting the car. First attempt the car was not registered, with no permit, with poor conditioned typres. Second attempt the car had FOUR NEW TYRES but the tow bar cover was suddenly broken but when I viewed the car at first all was fine nothing was broken. For days Suzette the "sales executive" does not communicate nor update me of any progress. Eventually I call her on the 4th of March after days of her not calling, she told me "she was not in the mood to contact me and besides the car is still not ready" only to discover that the car was at BMW for 2weeks for a quality check, relevant information that Suzette failed to inform me. Her manager contacts me with assurance that the car will be ready. Third attempt of collecting the vehicle the front grill is now damaged, again management assurances me that they will COME collect the car and replace the grill. In which that NEVER happened. Weeks go by, again poor communication from Suzette after several non-rep**** emails sent to her requesting for the grill to be replaced. Eventually the car is booked to replace the grill but the labour for the repair was not paid. When asked to why such poor service till today I am waiting for Suzette to call me back. Till this day the car is not registered with BMW and is reflecting with an incorrect license registration number, the tracker and smash and grab certificate still outstanding as per requested. The car was collected on the 24th of March, offer to purchase was signed on the 6th of February, a cash deposit of R100 000 was made on the 10th of February,today is the 26 of April and nothing has been fixed nor delivered without a fight. This has been the worst and disturbing service received from VW, McCarthy and Bidvest(tracker). If this is the type of service delivered just because I bought a non VW vehicle then I am very disappointed.
