Poor/Terrible service

I have been with dialdirect for the longest time. I was in a car accident in August 2022. The insurance then referred me a particular panel beater and I was given a courtesy car. As the 30 days for the car hire was approaching I called the dialdirect to ask how far the repairs are. I was then informed that there were back orders with the parts, I had to take the hired car back and drive my wrecked car for +-3 months. I was informed to take my car to the panel beater Monday, 19 December 2022 for repairs. I called dialdirect on the Thursday, 15 December 2022 to find out what plans do they have for since the car has to be repaired. I called them almost the whole day and the last consulted I spoke to, Lesego said Emmanuel will call me the same Thursday before 16h30 till today I am waiting for that call. I am now being inconvenience for their incompetence, they should not have asked me to take the car to the panel beater and given me the hired car if they knew the parts were on back order. It is December now I only have one, if I am to take my car to the panel beater how am I to move around.
