Given the runaround by the panelbeater and my insurer watches

I was involved in car accident in October last year. Discovery insure sent it to renew-it Randburg even though the accident happened on N12 just outside Fochville. I had to call daily to eventually get the car repairs authorised and actually done. i received the car back in December with some unacceptable errors.

I went back to have these attended to. After inspection and experiencing the car I discovered more problems. I informed both Discovery and Renew-it in writing. After about 2 months I provided a list of issues and pointed them out. The car was taken for a day and came back with 2 of the issues unresolved.

I have been trying to get these issues resolved and have communicated in writing over and over again but nobody is bothered.

Why does Discovery Insure have assessors? Why does Renew-It have quality control department if they cant do-it right 1st, 2nd & 3rd time? By the way as my insurer watches merrily without a care to ensure the matter is resolved to completion?
