Can Legal Action Be Taken After A Chargeback?

Location: KY, shop is in NC

Feb I sent a gun to a gunsmith to get worked on. I had bought what was supposed to be a drop in aftermarket part. It wouldn't work. I contacted the part mfg and after quite a bit of troubleshooting they said to send it to a gunsmith local to them to work on it bc they're "the best" with this stuff.

They basically didn't respond to emails, I like written proof but they suck at any communication.

They were supposed to get it running reliably supressed and unsupressed. Supressors add gas and pressure. It can cause problems.

8 months of having to call every 2 weeks to check because in the second month I didn't call for 3 weeks and they admitted to forgetting about it.

They finally say I think we got it working but it's very ammo picky. Also we couldn't find a supressor for it to test with... I let them know what mount it used before sending it out. Ammo picky is not reliable.

They said $500 charge. I told them, gunsmiths in my area don't charge for 1/3 of the job and while they spent time and money, I only felt comfortable paying $300 for a partial job. Nope 500, you can do payments. They said we didn't test it supressed but we think it'll work. If it doesn't call us afterwards. So I paid the $500, really $550, they said shipping was included and the total was like $525 ish but I later realized 550 hit my card.

Well, I get it and it's scratched up and doesn't run suppressed. Too bad, wouldn't address the scratches. Said they spent $1,500 on ammo and time since they normally charge $100/hr for work.

Asked them to meet me even part way and refund even $100 for scratches and it not working right.

Nope please stop contacting us.

Roger, that, I'll let the CC company contact them. I filed a chargeback for the full price. I'd been willing to put some patch up on the scratches but at this point I guess I'm going for a full refinish which eats up the cost I was somewhat willing to pay for a partial job.

Sent the gun back to the manufacturer to get put back to stock and not even using this BS part. (Yes, anyone that knows firearms, it was a FRT and trip kit for a PSA JAKL)

Idk if I'm going to win the charge back. I have photos and video of the scratches and it not working but the card company wouldn't take anything.

This shop is petty AF and took great offense to me calling them out on their bs. I had to ask them 5 times to tell me what they put in the gun and "Oh, I didn't know you wanted a parts list". Plus they kept the parts they replaced and I had to hound them to get it back.

Can they do anything legally after the charge back if I win?
