A bundled hotel and flight package falsely advertised on Expedia as a children friendly resort. Hotel subsequently changed to Adults Only. Expedia refused to refund my flight cost in addition to hotel. Spent over 5 hours on the phone over two weeks to get full refund from Expedia. A reputable company would have immediately apologized for this happening and corrected mistake. After all the call themselves Expedia.
I spend over $40,000 annually on travel and will never use Expedia again.
