Worst service by Tavcor VW

I took my vehicle to Tavcor VW,Mount Road,Port Elizabeth for service. They called me at 17: 00 telling me that i must come and collect my car because they are closing in 15 minutes. I had to take a taxi to go collect my car but when i arrived there it was already closed. They do not open on weekends amd i need to go to work with my car.
