Dispute Credit Card Charge From Contractor?

So had a plumber come out and do work thinking I had a clog due to a slow toilet We went from a $100 call to a "you need this $500 drain cleaning" to "you need a whole new line to the road because your pipe is collapsed" at $2000. At that point I send him on his way and pay the $500 with a card thinking I need a new line.(he asked for cash or check) I get my father to bring equipment over and we dig up the spot, everything is fine and figure out that my modad system has a drain field that he ran his drain cleaner in to. After some research and questions on the OT I get a second company to come out who knew about modads. He explains that I apparently need a lift pump.

First guy had no idea it was there. He would've dug up and destroyed all that if I'd let him. When I called him for the toilet and once he started going outside I asked him if I needed to call someone who knew about modad and he said no. To me this is incompetence which I couldn't recognize at the time because this is all new to me.

Called the owner of incompetence plumbing. He makes excuses. I offer to pay part of the bill because it was in good faith but because the plumber did the work when he obviously didn't know I didn't feel this was good service at all. He starts going on about me agreeing to pay a quote(which was an estimate). Tells me he would talk to his plumber on Monday and call me.

Meanwhile he goes ahead and hits my card which makes me think he won't stand behind his work on Monday. I doubt I'll get a call. But will Chase Credit stand behind their consumer on this even if the plumber has a signed paper saying I agreed to pay for a repair? The paper includes the inaccurate diagnosis. I've never charged back in my life. This is just bad work.

I'll call Chase on Monday I was just hoping someone had some experience. If you read all of that, thank you very much.
