Negligence

Hy . I'm a drive of POLO TSI. 1.2 high line. My car went for service last Friday on the 27-07-2018. There was no any problem in my car except for service cos I was reach my KM in the clock. After the service my car turbo was not in a good condition. I feel like they swipe my turbo. I m very disappointed about Ermelo VW. I was supposed to be at work from yesterday in Witbank, I didn't make it cos the car is still with them. I gave them yesterday morning. Today 1 of service advice phone me and said my be the car would be ready on Friday. Which mean the whole week I'm absent at work because of some 1 mistake. Eish I'm very very disappointed
