Renew It - Discovery - Ethics of Practice in dealing with their Customers

I took my car to Renew It in Randburg as advised by Discovery, my Insurer. Thats when my nightmare started. The first hurdle was dealing with the assessors, who approved some of the repairs and declined the rest, without the full understanding of the accident. Guess they operate on playing a '"game of poker with Insurer's clients. At the first attempt to collect my vehicle, which we were informed is ready, was far from that. The quality of work was poor, the panels were loose, the nudge bar we were told was replaced (new), yet there was clear marks showing that it was not. They even went to the extent of putting a clear tape of the sign to camouflage that it looks new. I refused to accept the vehicle and it was taken back into their workshop. The 2nd attempt was also the similar. On the 3rd attempt, more than 5 weeks later, the vehicle despite not being in a satisfactory condition. I noticed that my right side headlight was chipped, obviously when they had refitted it. When I pointed this out to them, I was asked for proof of this. After much debate they advised they will sort it out, as I could not find any photos, at the time. I later found emails from the first assessment of the Insurer, who's assessor had taken clear pictures of my car's headlights, proving that it was not chipped. I then sent an email to Renew It on the 8 April and was advised that it was escalated to management. To date, after much following up with no feedback, still no answer. Raised this matter with Discovery, sent them my emails of complaint to Renew It on 19 April and I am still waiting. Clearly, Renew It tried to conceal further damages to my vehicle and was hoping I didn't notice. Also got my car back with a flat battery and had to get a new one. This is AN APPROVED PANELBEATER FOR DISCOVERY!!!!!
