As I read the comments above I know that the number is from Hotel.com and I beleive that they or affiated with Expedia.
I have recently make a complain to Hotel.com that their represntative are rude and deliberately gave me wrong information. They are the worses comtomer sevice that I have ever experienced.
I received a call today with this same number, my girlfriend pick up and she got cuzz the hell out of her mind.
Thanks for the tips! Now I now is Hotel.com I definitely will do something about this.
