Kick You In The Face!

So I brought my car to the dealership today to get it looked at since it still isn't starting reliably.
I left 50$ poorer and pissed off.

The guy never told me on the phone that there was a fee just to look at my car yet that's the first thing he tells me when I walk in. "So it's just going to be 50$, like we talked about on the phone" Uh NO we didn't talk about it. All you asked for what my name, my number, and what day I'd like to come in on. THAT'S IT!!!
I told him he was wrong but that I'd be willing to pay it anyways because I need my car to be fixed and was positive it was something wrong which is still under warranty, in which case he would wave the 50$ fee.

The idiot couldn't even find my file in the computer from the last time I was there. I should have known at that point to ask to deal with someone else, like the guy I dealt with the first time I was there. But no, I continued with him. Anyways 15 minutes later he takes my keys and my girlfriend and I leave for lunch.

Fast forward 45 minutes and the idiot is calling me to tell me they're done. He is sorry to inform me but I do owe them 50$ and there is nothing wrong with my car. WTF??? So I ask him how this is possible and he says " I don't know the car started fine for us, anyways you can come pick it up and it will cost 50$." We go back and forth a bit on the phone, me not understand how they didn't find a single thing wrong with the car and him telling me "well you have a brand new belt on your car, when did you get that done?" Um.... I HAVEN'T.

 I may not speak car but my car is my baby and I know exactly what has been changed and done to it since I bought it and I'm the only one that has ever owned it, therefore I know my car! So the guy starts arguing with me about this and I tell him I'll be right over to figure everything out.

I get there and he greets me warmly and then he continues to tell me how much I owe, hello dude I heard you the first time! And so I start questioning how they can't figure out what's wrong with my car. He tells me he had a mechanic of 25 years look at it, it started fine and everything looks perfect expect for my automatic starter (which I already know doesn't work). He then goes on to tell me that I should go back to the dealership where I bought the car (2 hours away) to have them fix that and maybe they could figure it out. This is where I lost it. I told him firmly the starter hasn't worked for almost 3 years, it's never given me other problems in the car and I shouldn't have to drive back to where I bought the car to get it fixed, they should be able to tell me what's wrong.

This is about where he lost it! He started raising his voice at me asking if I thought they were incapable of doing their jobs, to which I replied yes! I told him he wasn't listening to the problem, clearly couldn't figure out the problem, and therefore was inadequate at his job. I snatched the bill from his hand, told him he was incredibly rude and that I clearly knew my car better than they did, since they couldn't figure shit out expect for to place blame somewhere else, and them cut off his reply by raising my voice to tell him his customer service skills left something to be desired.

YOU ASS!!!! Ugh he made me so mad. All I would have wanted was a polite "I'm sorry miss, we can't figure out the problem. Here are a few ideas for you to try at home to resolve the issue..." I just wanted him to listen instead of trying to tell me I was wrong. How can I be wrong when I know my car doesn't start in the morning and I'm always late for work or when I know there is a good chance my car wont start in the parking lot after work? I should make him come start my car one morning and then rub his face on the inside of my windshield, which is consistently frosted over every morning now, when it doesn't start.

So now I have no clue what to do.... If the dealership can't figure it out who the hell will?
