Chads auto repair

I brought my 1994 mercury grand marques to chads auto repair to switch out a transmission. He said the job would take in a few days on that my car would be done on that monday. When Monday came the car was not done but instead the transmission was 2 in longer then the old one so that ment that the drive shaft was to long. I had to take the drive shaft my self to get a inch taken off and was reasured that it only need an inch taken off. Two days later i take the drive shaft back to chads and instead of calling right away i called him a few days later and he tells me i need another inch taken off. I take it back to hedauls a second time and had the same thing done. A day later i take the drive shaft back to chads and it takes a few more days to get my car done and when we finaly went to go and pick the car up we find out it wasnt finished. He didnt finish tighing all the bolts for my manifold. We asked him why he didnt do the rest of the work and he told us that he didnt have time. So now its been a little over a month and im still trying to have him pay to fix my car whitch sounds horable.
