My New Job Screwed Me When Using My Personal Vehicle For Work

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.

The quote for the repair was for $2100 and maybe more because of the area it was damaged, I don’t have any written proof or audio of them promising to reimburse, but i plan to go up to the office this week to allow them to repeat their promise on audio

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.
