Orbitz Scam - Fraudulate Cancelation of flights On Line Internet

Trying to book air travel through Orbitz on United.....Orbitz had the lowest published fare for my family of three to travel to Colorado. The first time I got was entering my payment information and once I clicked conifrm, the screen went back to the home page and the banner said this reservation has been canceled. I reload the page and start over from the begigning, of course the fare was $100 higher now. I completed the payment sceeen and recvied confermation e-mails form orbitz. I loged on to United and confimred my reservation thorugh the United website. 1.5 hours later, I recived a "reservation cancelation" email form Orbitz. Highly angry, I called Orbitz and was shuffled around through supervisors, 46 mins in total, all saying that the reservation was cancel by somoen who had acess to my account. Orbitz tells me, you account must have been hacked? Yaaa, a hacker who wants to cancel peoplel flights. Total joke......posting one fair and wanting canceling peopls flight to force them to rebook at a higher fare.
