small engine specialist "lost" then sold my property pearl, Mississippi

My power washer needed the carborator repaired after having set up all winter. I bought a carb rebuild kit from Small Engine "Specialist" and the kit had defected gaskets which lead to gas leaking around the seals.  Initially, no big deal, I just vbrought the whole thing into the shop and asked them to fix it instead of spending any more of my own time on it.  Theboy at the countwer told me it would be ready in ten days to two weeks. After not hearing from them min two weeks, I called to check on its status. I was told it was still being worked on and it would be another week. after three more times of the exact same thing happening, I just asked for my power washer back. I was then told that they had no record of me bringing it in and I was out of luck. I went home and got my initial work order and brought it back and they said I must have already picked it up. I asked the owner if I could go in the work area and search for my washer and he said no. Later that day I went back just before closing and the owner was gone. Hence, I asked the boy at the counter if I could search for it and he said okay. Within just a few moments I found it and it had never been touched by anyone at the shop. A few momentsd later the owner came back and literally through a fit that I had gone into the work area. I told him I just wanted my washer back and he said it would cost me $30 to get it back because that's what they charge for a diagnostic check(which had never been done) I refused to pay anything for him to keep my tool for six weeks and do nothing to it but stack other peoples stuff on top of it.  He continued to scream at me and dropped "F" bombs just about everyother word. This Gnadless idiot then had a girl from the shop call me to tell me they were charging me $10/day for storage up to one more week and that they had sold it to settle their loss. My advice to anyone w/ a small engine problem in the Jackson MS metro area would be to find ANYONE else(up to and not excluding an untrained blind armless monkey) to "fix" your engine before letting this idiot rip you off as well.  If this idiot had had enough teeth to knock out without risking the likelyhood of contracting some terrible disease associated with third world conditions in his mouth, I'm pretty sure I would have.
