Motorcycle fabrication service near Stockton, CA

Thomas previously was doing business as PCS Marine in Pittsburg, California. I took my boat to him in 2012 to have an overheating issue diagnosed and he found out my 350 motor had been damaged by a faulty head gasket and needed to be rebuilt to the tune of $3000+. I told him there was no way I could afford that as I was recovering from Kidney Cancer Surgery and was all tapped out financially from not working. I told him that I would pick-up my boat and would just have to let it sit inoperable. Thomas called me back the next evening saying not to worry about my boat, that he had talked to customers/friends about my situation and that they had pledged enough money to pay for my motor to be rebuilt. I started crying on the phone at their awesome display of generosity and told Thomas to thank them all for me. He told me it would take awhile to do the work as it would be when he had free time from paying customers, to which I said that was no problem. I checked back with him every month or so just to see how things were progressing and even paid him $800 as he said my engine block was bad and he had to buy a rebuild-able core motor. He eventually sent me photos showing my boat with the old motor removed and the new motor sitting next to it on a stand. After nine months, my boat still wasn't finished so I called to talk to Thomas and he started yelling at me and told me to come get my boat off his property. I went there and saw he had put my old damaged motor back in my boat. I tried talking to him but he just started cursing at me and told me to GTF off his property. Thomas Schmidt stole $800 from me in addition to however much money his customers/friends had given towards repairing my boat. In the unlikely event this horrible person is still in business, don't let him con you into being another victim.

Can you guys fix my pocket bike??
