Disgusted customer

I took my vehicle to eastgate Renault for a service and informed them my vehicle needed checking on a default light. A day later I was informed that it was my battery .wrong.diagnosis .had to use tow trucks to take the vehicle back to Renault eastgate They then rediagnosed the vehicle after 3 days and informed me.it was the clutch kit which needed replacement.once again wrong diagnosis.iI was given a quotation of R14 000 and was told the warranty did not cover the part. I REQUESTED for a courtesy car but the manager said he couldn't help me.i have been.taking Uber every morning and evening as a result of the unprofessional assessment I moved.my vehicle.to a.differnt. branch out.of.poor desperation.and before i become insane I'm.truely disgusted.that this dealership is not able to.make.proper diagnosis of a vehicle. This.branch should be.embarassed about the poor service offered to its customers.
