Car rental company is threatening to send legal debt collectors to my house, what should I do?

Hi, I’m currently in a sticky situation where my current company which I have a contract with is refusing to fix the car which I use to work.

Context: I am required to pay weekly rentals until the contract ends which is not until next year April/May.

I had gotten into an accident about 2 weeks ago (fault was with the other party), and ever since then the car has not been fixed.

The company has openly stated that they will not fix the car, and have requested that I come to collect the car in its damaged state as they “do not have enough money from the insurance to repair it”.

Furthermore, the car is somehow more damaged than before and I have photos to prove it.

As I do not want to use the damaged car and the company does not want to fix the car, can they actually legally pursue me?

As far as I have read, no where in the contract forces them to fix the car, and therefore do not know if I have any legal highground here.
