Repair Delays by Dent Doctor Randburg and Outsurance

My Husband was involved in an accident beginning of March, He was hit by a drunk driver and our car was towed to Dent Doctor Randburg, It's been there for 2 almost 2 months already and the repairs have not started yet, I kept following up with the repairer and they kept telling me that they're waiting for parts eventually last week I was told that the parts will arrive on Wednesday the 10th of April I followed up again at first I was told they're awaiting parts when the receptionist told me she can't help since their service advisor is on lunch then I insisted on speaking to someone they then put me on hold then eventually told me that they will get someone to assist me. A lady came on the line and told me that parts have arrived on Wednesday but they can only start with repairs on the 17th of April, I don't understand why the repais have to start 6days later, The car is outside getting rained on and there was a storm last week and it was kept outside. They're telling me that the car will take 10days to repair , which means it's going to be ready by month end yet if they had started this week they would be done before that.
