Sandton renewit is a ****

I had fixed my car with renewit Sandton then it was issues after issues the work they've done. However they pride themselves with a warranty on the with they've done but this was not the case with me, they always say they never worked on the part. Fir example thay replaced a sill cover when I told them it's loose they said they didn't work ok it and I had to proved email chain as evidence. Now I have another issue agai they never worked on it yet they did but not to mention them living my car stripped with parts on the floor and gave me my car like that. I'm beyond disappointed with them. They must just check if they still "renewit"
