Complaint Review: Priceline.com

I tried to book a room on Priceline and they advertised a price that I agreed to and clicked to book room button.  After entering my billing info, I was transferred to my Paypal account for billing.  I authorized the billing and was transferred back to Priceline only to end up in an endless loop of my transaction was processing.  After waiting for 20 minutes and getting a website not rersponding error, I clicked out of that screen only to receive a message from Priceline that the room was no longer available at the rate advertised, but if I wanted to pay $80.00 per night more, I could still get the room.  I declined and checked my Paypal account only to find that although the refused to sell me the room at the advertised price, they still tied up the full cost of my booking in my Paypal account.
