Bad service / Hiked prices

I took my car for a service to this establishment. They charged me R8700 for an Opel Corsa service ( major) - which is more than double the quoted price by other companies. When I refused the service, I was then charged R1200 for diagnostics.

They inflate prices and **** people. The service assistant was by Adhir Hiralal . He is also mentioned twice in other reviews. Please be careful with establishment.
