C & L Transmissions

[redacted] of C& L Transmissons agreed to fix my Ford Five Hundred transmission for $450 plus cost of fluid plus tax. He now want more than agreed.
He called me to bring my car that the transmission for my Ford FiveHundred is ready to be put in my car. After my car was towed to the street beside his business because the Tow truck was not able to go inside his garage. Mr. [redacted] called me 2 days later that transmission he accepted was not the right transmission for my car. I contacted the transmission place to send another transmission to replace th first one. The company shipped another transmission to Mr.[redacted]. Once again he accepted the transmission from the company as being the right transmission for my 2006 Ford FiveHundred. Mr. [redacted] told me again two days later that transmission that he accepted was not the correct transmission for my car again. I contact the company once again to replace the transmission, of which they agreed to do. Later Mr. called that he was going to charge me $20 for storage. I told him that I was not going to pay $20 for storage that I will pick my car up. When I visited his shop to get my car, the car was lucked up inside his garage. I called again about picking up my car. He said I need 4-5 strong men to push my car our of garage. I told him that if he want's me to tow my car, to place my car where it can be towed. He never did.
After he received the third transmission I called him. He said the transmission is good this time, and that my car would be ready in about 2-3 days.When I called 3 days later to check my car, he said" your car is ready" I was happy until he said that he was going to charge me for storage. I told him that I did not agreed to any charges for storege, and that my Ford FiveHundred was not left in his shop due to my fault, that if he had not continously luck my car in his carage I would have been able to tow it. He said I should have brought men to push my car. I have never had of any mechanic or transmission shop requesting customer to bring people to push car out of his garage before they can get their car.Since Mr.[redacted] failed to make my car accessible to be picked up, and he was responsible each time for accetpting wrong transmission, and my car was not abandoned I should not have to pay for any storage charge.
