window tinting

I am very disappointed with my experience with this company. I originally called to ask for an estimate for getting my car's windows tinted back in August 2011. I had never heard anything bad about any of the local tint shops, so when he gave me the lowest quote, I decided to jump on it. I am supposed to drop my car off at 8:00 am to get it tinted, and I have a family member follow me there to drive me home. I arrive a few minutes early, knock on the door, but there is no one to be found. No one shows up until a quarter after. I hand over the keys, and get a ride home. Later, around noon, he calls me to tell me my car is ready. I get a ride over only to discover he does not accept anything other than cash. I tell him I'll go to the atm to get cash, and on my way there he calls me to tell me that I am wasting his time, that he has obligations and that I need to hurry up. I come back, pay, and leave. Two weeks later I leave for school. While at school I notice several imperfections in the back window, including two areas where he tinted over dirt on the window. Over my winter break I ask him about getting it fixed, he tells me to come by on a warm day and he'll see what he can do. I figure, alright, I'll come back during the summer and have it fixed. Fast Forward to June 2012. I show up and he agrees to fix the window next week. I have to call in to reschedule because I have work that day, and he says he won't be able to fit me in the rest of the week. (Note:I called in three days before my appointment.) He says no problem, come in when you know your next schedule and he'll take care of it. I show up on my second appointment, ready to drop my car off. He is finishing a pinstripe on another vehicle and tells me that he is going to have to charge me forty dollars for the warranty work. His reasoning is that I stood him up twice. I told him that I was not going to pay him for what should have been done right the first time. He then begins to lecture me
