Your name might be blacklisted. Have friends that book directly from expedia and after a certain amount of times, it will ALWAYS get cancelled under that name for the reason of it being blacklisted. You must change website (tons of other websites are owned by expedia too, so you must do some research to find one that isnt). Also, using a different name works too. Dont use the same email too. Different bins doesn't have a play in it. Go look for privately owned websites (airtickets24.com, etc) there is a couple other things, pm me and I will help you or book for you for free.
