No good customer service

Car service city Hello I last took in my car to car service city in rusteburger they diagnosed it they told me the CV joints and shocks need to be replaced then once the parts are replaced the clicking noise will go away, they replaced the parts still the car made the same horrible noise, the time I return they car they now say is tirod ends and buljoints, I left the car, two days later they tell me to fetch the car, I took it it still had thr same clicking noise, I returned it even, they then say say its the gear box, I took it the car for the gearbox to be checked they told me the clutch and gearbox is ok, I then took the car back to car service city again they then tell me it's stablizerz, I live the car again by them the other time I fetch it, they tell me again it's the gear box and the gear when they put it on 4&5 it makes a loud noise. So this people at car service city don't know how to fix cars and the have bad customer service. They even cut the wire of my airbags
