Momentum/Renew-It headaces

My claim through Momentum Insure landed me at Renew-It, Randburg, and I went to the company and paid them the amount paid to me by Moentum for the repairs. It a week before my car was scheduled to go in. I asked them to order the part (a door) to be ordered in order for the work to start immediately. However, a week after my car went in, I went to the company to find out what is happening. I was told that the door is on backorder and it will take four to six weeks! Why should I be woithout my car for a week? Yesterday I received a sms that my car must go in on Thursday, 4 July 22024, however today I received a sms: "Your car has no been moved into the Panelbeating dept! My car is parked at my house! I have send Renew-it several emails requesting an explanation, but never received any.
