Charged for work not done

I took my car to have the CV joints replaced at Supa Quick Claremont. they claimed that the cvs were changed but the car is still making the noise when turning. I have sold the car and the owner is now claiming from me. The Manager at Supa Quick is rude and arrogant and refuses to assist me, he referred me to MRI. Wonderful customer service SUPA QUICK!!! The new owner lives in bloemfontein and is unable to bring the car back. this unacceptable behaviour by Supa Quick, all he had to do is refer me to a branch in Bloemfontein for the car to be checked. <br> <br>
