Poor workmanship followed by empty promises

My car was taken to Renew-it Sandton by my insurance. It took them almost 2 months to fix my car. When I collected the car there was a dent on the rear door that the assessor and Renew-it missed. After a week the insurance approved for repairs and I took the car back to Renew-it Sandton. The dent on the door was repaired but less than 2 months later the door strip on the door that was repaired fell off. I informed Charity and she promised to add me to the courtesy car list for end of October and collect my car to correct their poor workmanship, that was on 13 October. Almost a month later Charity never contacted me, I'm still driving a car with a lose door strip, the strip they damaged while repairing the door.
