My new job screwed me when using my personal vehicle

I started a job earlier this year around July as a supervisor for a small company doing fiber internet installation for larger internet companies. This company offered a salary position and a company truck in my future of being employed. I live in Houston, Texas. My personal truck was damaged in that short duration of being employed while i waited for a company truck as they promised. The company has since fired me only a few weeks after the incident, They stated they would reimburse the damages when it happened and even restated it when I was terminated, promising to pay the shop fees. It’s been 2 months since, with very little communication with them. I’ve sent repair quotes and such and they even offered me back a job a couple weeks ago but have been ghosted me ever since i brought back up this repair clause as a term of being rehired. I’ve been left in the dark in terms of communication and my vehicle has been left unrepaired for several months.

Can i pursue legal action? Or Is it a waste of time?

P.S. I was on “at will” terms with this company but was never compensated for out of town trips that were more than 3 hours away.
