Kayak.com They put my family in danger Internet

I booked a hotel room on 3-9-2013 thru Kayak.com, Showed up at the hotel at 10pm after a long and tiring day a theme parks, clerk says they are booked solid and he remembers speaking to a kayak rep earlier that day about me, they told him they would call me and reschedule (which they did not). So I call Kayak.com they say they are very sorry and will check into the situation and call me back. Its now 10:30pm receive call back they are going to refund my money in full and great news they found the last hotel available in my area if I want to book it, it will cost me double what I've already spent. I tell her that I do not have any more money. And she says she is very very sorry but there is nothing they can do. After going back and forth for a bit she agrees to contact a manager, its now 11:15pm. I wait on hold for 15 minutes she gets back on the line and say the manager is busy with other call and she left a message for them to call me back shortly I ask how long she say within 10-20 minutes. I waited till 12:30am them called them, spoke to another rep he pulled up my account and said let me see if there is a manager available, on hold i go 30 minutes and i finally hang up.  I have no more money for a hotel a car full a family and I cant keep my eyes open to drive home a 3 1/2 hrs drive. Bottom line they put my family in danger.
