Vw centurion autohaus

Hi would like to lay a complaint about vw centurion autohaus my wife and I bought a polo vw highline from them 6 months ago brand new yesterday the EPC light came on and the car was towed to vw centurion we asked the guys at vw to lend us a car because we only have one car to go to work and they refused and said they dont have any cars to lend us .our car is still new it's not like a old car we had and its giving us problems . Our sales rep DK tried to help but managers there refused to make a plan to help us out . I will never buy another car from them again and I have been going there for the pass 5 years now
