Online Travel Booking and Bidding Agencies - Priceline.com: Help Resolving Dispute

I have had a recent awful experience with Priceline.com.
Every agent that I have talked to (requiring a near act of God to reach a human-being) has read from the same script. Nope, can't help you.

Has anyone had any luck resolving a dispute with Priceline.com? I am counting on some help from American Express, but would like to have my ducks lined up.

Thanks!

Well I have a dispute with priceline from a week ago. since I can't get through to them, I'm just going to dispute the entire bill and force them to talk to me or have a free stay, pardon my language but screw them if they are going to give us p*** poor service.
