Non Interested in small business

My car went in for a minor repair to the front bumper at the beginning of October. It wasn't ready for collection as the bumper had not been aligned. Two days later, after an intervention from the insurance assessor, it was ready. One day later, a warning light for a front fog light appeared and is yet to be repaired. After another intervention from the insurance assessor, it was established that the light, which the workshop staff discovered during the repair process, was not related to the accident damage. There was no attempt to communicate this to me. After discussion with the assessor, Vernon, the Workshop Manager undertook to fit the bulb and cover flap, which would be for my account. Despite numerous emails, promises of return phone calls and follow up, no quote has been provided and no return calls received. I assume Renew-It are only interested in the well-paying insurance work they do, even if they don't complete it 100% the first time.
