Expedia customer service is really disappointing. I booked a round trip flight for my parents visiting USA from India and back. They took the flight from India to USA. However, for the return journey, it was a three leg flight (rdu-jfk-del-ccu). The first leg which was supposed to be operated by Delta was canceled by the airline itself. As expedia couldn’t provide us any suitable connection to jfk, we had to cancel the entire return flight. They are refunding us only the base fare and deducting more than half the fare(taxes+cancellation fees).While trying to make a fresh booking from IAD, they are also charging the difference amount in fare+ rebooking charges per person. So basically, we are losing a huge amount of money now. Neither they are successful in providing a suitable connection to jfk, nor they are agreeing to refund our money. I would never again do business with expedia. Going with Kayak or booking directly from the airline website would be a much better idea.
