Unbearable Service experience,*********,****med

I took my car to VW Midrand a couple of times only service between (2014,2015 &amp; 2016) upon every collection is my car is tampered with <br> <br> Processes are mismanaged, I take the car in for service and immediately after driving out something breaks there and there on all encounters, All 4 attempts I took my car for service not problems new problems are discovered only on my way after pick , is it so much of a coincidence that a car breaks down every time you have a service done , talk about timing , it occurs like someone had triggered a fault so that u return sooner enough , strange when you diagnose the car no errors show initially furthermore the Service advisor are super *********** or just covering up the mess, My car was 100 % before they touched it now I am more afraid to even take my car to any VW dealer considering the round abouts, you can take a brand new car there I can promise you a service advisor will contact you regarding all the maintenance required in the car even if it has been driven, I have had back &amp; fourth with the manager but his only logical explanation is that cars break all the time without even having a proper , thorough investigation to diagnoses
