I've never been so pissed!

This hotel sales rep I'm using thru work is trying to screw with me. She keeps going back on her word. Screwing shit up. Revising the unsigned contract--because she hasn't given it to me to actually sign. Yet, I had to send a out an invitation to the event since it's NEXT WEEK and then she blindsides me with a $2000 price increase! WTF. My head is killing me now. She just got an earful and is now talking to her boss about bringing down the cost to where they were YESTERDAY. Ugh!
