My car was booked in for repairs with renew-it Randburg for replacement of the plastic part of the bumper and replace sensors etc. the car was booked in 7 Aug returned 18th September. Upon taking delivery of the car on my way I noticed that something is moving in the boot I informed them & was promised a call back. No one called, I then find that my car has multiple scratches where it looks like the top part of the boot has been scratched including the lights where it is not naturally possibly to scratch the car unless the boot was & dragged across a hard surface. The damage to my car was minor but now I have scratches going up to the roof of my boot. Called 3 times today was told the lady assigned to my car is not in when I asked for a manager im placed on hold & subsequently the call gets dropped. Beyond frustrating that I had to be without a car for over 6 weeks only for it to come back with damages & no one wants to address this. I have had nothing but a painful experience dealing with this company.
