Lying about what was wrong with my car

Motor Enginnering (Cnr Stormvoel Road and Hans Dons Road, Kilnerpark) is an ************* business. I took my car in for repairs and they said that my head gasket was blown and quoted me R5000-R7000. It took two days for them to even look at my car. This made me very weary, so I decided to trust my instinct and take it to another mechanic. Turns out my gasket is perfectly fine, it was a burst water pipe. Motor Engineering were trying to completely rip me off due to my lack of car knowledge. When I phoned and confronted them, they just made up excuses. Please avoid this ***** mechanic!!
