Here's what I would do. First, remain calm, free of emotion. Explain to the owner of the shop you're not going to just "go away" and neither has the problem. Explain to him that you see yourself having two options at this point. One is giving them the chance to do the job the right way, pay what would have been the cost of doing it that way if it exceeds what you have paid already (crediting you for the $1400 you have spent) and get it fixed right or you'll be forced to start over elsewhere, file a claim in small claims court and sue him for a refund of what you have paid him thusfar. Tell him you'd rather try and work it out as gentleman but the fact is that is what small claims court is there for and it is a very easy process to sue him with very little cost out of your pocket.

I wouldn't hold out much hope for the credit card company siding with you at this point but you never know. The problem is you can dispute the charge but I don't think that doing shoddy work is grounds for them intervening and reversing the charge.

If you had not received anything for the payment (i.e. he said he was ordering something for you which never came in but he charged for it) then they would reverse the charges but he will claim he did the work and he's willing to resolve it with you (whether that is true or not) and the credit card company will be out of it, at least that is how they will see it. Still it is worth trying and seeing what happens...be advised you have only a limited time window to dispute a charge so you need to move fast if you plan on doing that.
