Outsurance and their service provider has put me through hell

My car was involved in an accident about 3 months ago and they took it to Ben's penalbeaters. They received the car parts 4 weeks after they got the car and when I asked how long it will take them to finish it I was told 10 working days, when I asked for progress the following week I was told they have ordered other parts because they didn't see that much damage on the car, so it will take 2 to 3 weeks to receive the parts. The parts were received in 2 weeks. Last week Wednesday the 26th of July the lady from outsurance called me and said the car will be ready on Friday, and again on the said day 28th I call the lady to confirm and she said the penal beater will call. They didn't, I called the guy said they closing at 17:00 so I can come. I got in a taxi to go there, on my way the panel beater calls and say the car has a bigger size part so he is sending someone to go get the right part from Hyundai but they will work around the clock. I get there disaster, my car is not ready, am told the part was damaged. About 3 months later still no car, no eta but I am the drama when demanding my car.
