clay combs tire services Burnt me on my truck repairs .. eldred, Pennsylvania

I brought my truck to this place on march 5 and they was suppose to work on it and they didn't end up geting it in the shop till march 20th and yet it still sets down there no fixed and they haven't even found out what the problum is and it april 14. Last somone has talked to them they aren't even going to work on it again till next week sometime. Now I don't know if they don't know how to work on a diesel or what. But they should have never took the job if they couldn't do it in a promp and professional manor. There is no reason why my truck should have been there for over a month and no one knows what is wrong with it.. idk if there is something I can do legaly about it but I am looking into it too see. If anyone knows please tell me.
