I booked a vacation package on 6/23/21. My credit card was charged $3, 726.84. I cancelled the trip within the 24 hour window required to receive a full refund. I received a refund via my credit card on 6/24/21 for the hotel which was $1672.30 and for the trip insurance $276.06. I have not received a refund for the airfare totaling $1778.48. I contacted the airline (United Airlines) directly and was told that my credit card was not charged. Expedia's practice of holding funds for 12 weeks or longer prior to a refund is unethical. I cannot reach anyone at Expedia to discuss my issue.
