Bad service from Santam

We have had insurance with Santam for many years. We have always been very happy with the the service. People have always said we pay alot but we felt it weighed in the in balance, because if our car needed to go into the panel beaters we would have a hired car. This time round I am disgusted to be associated with them. We received the hired on the 11th of July 2022 I received an sms on Monday the 8th of August 2022 to say the hired car needs to be returned on tge 10th. I queried this with Santam as the Panel beaters has not yet started the repairs on our car. I was told that they can not extend the car hire. I asked the question so you are leaving us stranded, the answer was yes. Unbelievable. You take my money every month but no one is willing to go the extra mile. My husband's job is reliant on him having a car hence we took out comprehensive insurance. I was also told its not their fault that there is a shortage of parts. Is it my fault then. After 20 years of not taking a bus or taxi we are left stranded. I am so disappointed 😞.
