Help!!! I'm Melting!!!

HELP! My air conditioner blows HOT air!
No, I'm not just complaining because it is not "cold enough". It is not cold at all... It is not cool... It is not even warm!! IT IS HOT!!!!! I live in Georgia and we haven't even come close to what we consider "hot" down here. But with the temperature being in the high 80's (for now) it gets pretty damn hot inside a car that is blowing hot air. I've tried EVERYTHING! and the P.O.S. air conditioner will not even turn off, which makes me wonder where the problem really lies. My engin temp is normal, my car has never overheated, No signs of any real trouble untill now.
Please Help Me!?!?!? I'm pretty sure I could catch on fire and melt away any day now.
