Cottman Transmission Ripoff Artist Independence Missouri

 I had my car at a transmission shop and as I called around to find the more affordable option I ran across Cottman Transmission. I called them they then quoted me a specific price which I was happy with, a free tow to there shop and free diagnostic check. After my car arrived I went to Cottman to put 1000$ down on the balance, I did not need to seeing how the diagnostic was free and they said I didn't have to pay till the job was completely done. The agree on price was 3600$ minus 1000$ left a balance of 2600$. Cottman then called me a few days later after they found the problem, it was a clutch drum and it cost 1200$. They then said I needed to pay for it and it would be added to my balance, even though that should of been part of my free diagnostic check. I told then I couldn't afford it and to stop working on my car. They then returned my car with the transmission in boxes sitting on my trunk and refused to return my 1000$ saying it paid for the work they had did. Then only work they did was locate the problem which should of been part of the free diagnostic. They returned my car in worse shape then I had given it to them and stole my 1000$.
