Alignment

This is my first time came in this place for doing four wheels alignment because I saw price $45 alignment advertisement in the front. So I asked them how much for 4 wheels alignment? they said $45. After seat in nasty waiting room little while, I decide it's better to go out site for more fresh air than in that room.... They came out say my car's done. After paid for labor, I came out and look at paper, they realized they did not do rear alignment. I went back to ask them, they said my car can not do rear alignment because there is no camber bolt...so whatever. I said are you guys kidding me? I said it's there, it does... and then he turned around said we don't deal with rear alignment... I said I asked before I handed my key to you guys.... they said if I want to do rear alignment, I needed to pay for it.
