Care Clinic the Glen Leak of customer service damaging cars

Pathetic Services from Care Clinic in the Glen after spending R5000+ on my car service my mileage to gauge indicator for my fuel isn't corresponding but was working fine all the previous times when I had taken it to other services houses and Rian Oostherhuizen tells me it's impossible that the mechanics did something wrong before I had left the Saturday when I received my car I had told him to check that something is wrong, not forgetting that my gauge was working fine the morning before I had given my car to this idiot for a service and never had a problem in the past since I have purchased my vehicle and now instead of fixing my problem which was caused by one of his staff members his not taking responsibility is this another ********* house in the south to rob none whites as I have never had any problems like this when getting service at North of Johannesburg services providers
