The A Team Appliance Repair review: Scammed me out of $500

I called this company to repair my gas stove, which was not working. They came on Sept 2 and said the repair would cost $1419.51 and would be completed by the end of the week. They required me to pay $910.80 on that visit. I did not hear anything for several weeks. They finally returned on Sept 28, but were again unable to repair the stove, and they left after having created two bad scratches on the front of the stove. I emailed the company on Sept 29 letting them know about the damage to the stove and did not hear anything until Oct 14. I emailed again on Oct 21 and requested a refund, since after six weeks I still did not have a working stove, and no information about when or how it could be fixed, and additionally I was left with more damage. They offered to refund me $408.17, which means that I still have paid $500 for their work, although my stove still does not work. As of today, however, I have again not received any reply, nor any refund. I'm pretty sure their email communications are done entirely by AI - they don't really make any sense and have no understanding of customer service. If I could leave a zero star review, I would.
