Service City employee ran away with my money.

Car service city employee ran away with my R6000 and never fixed my car. I'm very disappointed in him as he approached me to fix the cap gasket and stop the vehicle from over heating, he made it worse and put my life in danger, I was stuck in four ways and had to call my insurance to tow the car after he has assured me that it was fixed ,this was in November last year. He made the car worse its not even moving, his name is Tumisho Protea Glen Service City.
