Bad Service and No cct of responsibility

On 23/09 my car went in to Lindsay Saker Fourways for a clutch replacement. on 25th, I received my vehicle back. That very weekend, I was left stranded as I couldn't get into some gears. After complaining to VWSA and the dealer, I learned that the workmanship at the dealer was poor as they didn't tighten some bolts. A week from there, I noticed an Intermittent fault whereby I couldn't get Reverse gear and 5th. Clutch also now seemed to be as problematic as previously. I then lodged a complaint to VWSA, spoke to Mohammed on the 19/10 and he assured me that VW will resolve my problem. On the 21/10, I get a call from the Service Consultant at Lindsay Saker, advising me that they will sort it out, but I had to wait for a Courtesy vehicle to become available. Kerri sounded like this problem was caused by me. This issue started off with the dealer whom didn't check their work in the first place. 2 Weeks now has passed, and I have not yet received any call from either VWSA or Lindsay Saker Fourways. This is the worst service I have ever experienced with VW overall. I have been driving VW's for the past 10 years. I will never buy another VW again due to the pathetic service they offer.
