Car Services and Repair Useless

VW Menlyn McCarthy is the most unreliable service and workshop ever. We buy a brand new VW POLO and there is something wrong since day 1 with the locking system. We did call and bring in the car for more than 3 times. All 3 times we could not walk out with a smile. There is always a problem. Then they did order the wrong locking system, then the workshop operator is not there to fix it, then the locking system don't fit. So all the time there is problems. They just keep quit till you need to get your Car late 17h30 and then they come with some explenations. All the time they say please bring it in again. So we are fed up. Never go there because their services is useless. Locking System is after 2 year still not fixed.
