I went searching on google to see if anyone has had the same experience as me and low and behold I found this forum and looks like expedia hasn't changed a bit! Booked $5000 trip through expedia only to find a preauthorisation amount of $5000 taken from my credit card, plus the actual cost of the trip! So I have been missing $10000 from my credit card for 17 days and I ring up expedia and say hello my preauthorisation has never dropped off. All I get is a so sorry I will contact your bank and request the preauthorisation be dropped off. 2 days later im still waiting and hoping my funds will clear. What a ridiculious system expedia, don't charge customers twice for one transaction.
