hotels.com hotels.com, expedia.com Incompetent and fraudulent Dallas, Texas Internet

We made a reservation 5 months in advance, and 2 days before the trip we got a mail that they had rebooked us to another hotel. Just like that. But they messed up that one too. Even after 4 full hours on the phone they haven't yet managed to fix anything even if their web site states that many hotel rooms are available in the place we are going. Seem that hotels.com is somewhat of a hoax, they are advertising hotels that you actually can't book and are stating availability that isn't there. Their customer service is incompetent and seem to be most interested in taking your money and not fixing your problem. I see that there are many angry people writing bad things about this company, do hotels.com even have any satisfied customers?
