Hatfield VW Rivonia terrible service

This is the first and last time I buy a car from this dealership! Service from the sales person was outstanding... But then there was an issue with the contract which costed us to drive all the way to the branch to correct it...I have the Polo Vivo 2019 comfortline model for about 3 months now and already experiencing problems... The window mechanisms were faulty, the brakes and suspension as well... Firstly it was a struggle to get the car booked in for repairs... On Tuesday 19/02/2019, the driver from the branch fetched the car for repairs from my husband's workplace and returned it later the day... Everything was sorted out but then my husband noticed that the front bumper of the car was damaged... He called the manager to notify him about the issue... He is now indirectly blaming my husband for the damage to the car... Requesting video footage from my husband's workplace showing how he drove the car from the outdoor parking area to the ba*****t... He parks the car everyday at work so why would he damage the car all of the sudden? Is this how they treat customers once the deal is done? I am totally disgusted by the service received at VW Rivonia! I regret buying the car from this dealership!
