CV City Vereeniging just lost a loyal client

I am not happy with the service received from CV City In December 2022 they "fixed" the cv of our car. We got the car back and still the car made the same noise. Then we took the car back and they checked the cv and said that their is nothing wrong with the cv but they did put extra grease in. But still the car made the same noise. I took the car to a mechanic place and they said that the cv was faulty and then i took the car back for the 3rd time and they " tested" the cv and said yet again that their was nothing wrong with cv. The noise got loader and the whole car vibrated then we took the car again to another mechanic place and they also said the cv was faulty. Then we decided to buy a new cv and the last mechanic replaced the old cv with the new one. The mechanic showed us the broken pieces of the old cv, as he took out the old cv all the broken pieces fall out, he said some of the pieces was missing( disintegrated). After they installed the new cv the vibration and noise was gone.
