I cancelled a roundtrip booked on Expedia from DC to Chicago. They claimed I had actually booked two separate one-way tickets, which I had not. They then refued to refund the most expensive leg of the trip, as if I had somehow cancalled just half of a round trip. I spent well over an hour on the phone. I spoke to two supervisors. They were entirely unsympathic and of no help except to waste my time. Do not do business with Expedia.
