AAAMCO review: Complaint

On april18 itook my car to aaamco at central and west st. I drove it there with 3 codes. They took car and did something I dont know what and when it was time for me to leave they brought me my car and with me standing right there the guy still chose to turn my car off and hand me the keys. I got in turned on the key and my car wouldnt start and now it has 5 codes I was furious.. Didnt say anything to them. Besides the 2300 dollars I had to give them for the work that they did which I know the transmission didnt need to be overhauled they did it when only a simple solenoid could have fixed it. What can be done?
