Kayak.com deserves a 0 for the worst customer service on the face of the planet. I used Kayak.com to book a room at the Willard InterContinental in Washington D. C. and soon after booking found out I wasn't able to go. After calling Kayak.com trying to cancel a full month and a half before my check-in date they said no. So I called the hotel explained to them and they said there was nothing they could to do, but if I had booked through them they said i would be able to cancel. I took my case to the Better Buisness Bureau and after 3 days of complicated transactions from Kayak.com to me the BBB said they couldn't make the company give me my $621.73 back. So now I'm out $621.73, running out of time, very upset at Kayak.com, and never plan to use the travel agency again.
