Paul's Mobile Mechanic Scammed me St. Petersburg Florida

Paul arrived at my home and did the diagnostic check he then proceeded to tell me it was the same code that I mentioned to him and sent a pic of through text message. He quoted me $450.00 plus the part which came out to be $125.78 he gave me a story that I had to call them and pay for it myself something to do with theft at that particular store. We scheduled for him to come and repair my car once he arrived he lifted the car on one-side and claimed he couldn't do the repair because the part was above the transmission which I found kinda odd but I am not a mechanic so he went on to tell me that the price would go up because of it and he would need another person to help him(That is not true). The price now went up to $700.00 (which of I had to give him a deposit of $300.00) and I would need my car towed to his home. Once the car was supposedly repaired he asked if I could Cash app him the balance since the other person that supposedly helped him fix my car had to go trusting this man. The next morning after picking up my car from his home the check engine light came on again. I took my vehicle to get a diagnostic done to it again same code so just to get another opinion I took it to another location same thing same code. I text him to let him know what happened he responded with send me the code I did. He then proceeded to tell me it could be a sensor same thing is happening as prior. We went on with him asking me to send pic codes so I did and I then asked him could the part you installed be defective and I never heard back from him again.   I did come to find out that my car was never really fixed he installed zip ties to the part he supposedly fixed which I have pics of. I even asked him could the part he supposedly installed may be defective and he said no but how would he know if he didn't even offer to do another diagnostic check and even tried to look at my car again? So I had another location do a diagnostic check same code was given. I text him letting him know once again that he requested I send him the pic of the code again I did and I never heard back from him. I paid Paul's Mobile Mechanic  $900.00 and my car is not fixed. He didn't even offer to check the car out to see if the part was defective or not. He went stealth on me. I had to end up taking my car to the mechanics again to where they found zip ties holding up the piece he supposedly fixed and installed in my car. It has been over 2 weeks since my last text to him and I haven't heard anything from him via text or phone call. He has completely ignored my last text to him.
