Unbearable Service experience,*********,****med

Worst experience ever,Initially booked my car in 4 Cam Belt Service but instead Oil service was done without my concern,misled it was required and the Cambelt service not done as requested,in the process I had my entire clutch kit broken down, had a quote amounting to 23k , second encounter I booked in for service & follow up call advised that my car had an oil leak yet there was no light indicator nor required any top up and again different Service advisor says now Cambelt needs 2 be done after being told it was perfect on the previous visit , third encounter book in for service last week and I was informed the car had a water leak no lights showing nor top up required before checking in,however diagnosis did not show any error messages, on all encounters new problems or faults were inflicted so that I return next day and I'm informed they might have tampered with the stuff by mistake yet informed by the service advisor that the car is 100% every pick up ,Every time after service I pick up new faults codes but advised everything is perfect upon pick up even strange that my car was diagnosed before I booked in with no errors,is this some moneymakingscheme,emailed de manager no joy
