Orbitz review: Refund on refundable tickets

On 8/22/22 I booked flights from Tulsa to Cancun and return (2/11/23 - 2/18/23). I realized as I finished booking that there was a more suitable return flight, so I cancelled the return flight and rebooked it. I subsequently received a refund on the cancelled flight. When I booked the flights, I specified “Main Cabin Flexible” for both flights, which was described as a refundable class. My confirmations from Orbitz clearly stated that the tickets were refundable.

On 9/17/22 I rebooked the flights for earlier dates (1/7/23 - 1/14/23), again selecting “Main Cabin Flexible” and paying a higher price for the refundability. The new bookings were lower in price than the original ones, and I received refunds for the difference.

On 12/30/22 I cancelled the trip, but the confirmation showed that I was to receive flight credits rather than a refund. I contacted Orbitz via chat on 1/7/23 and the agent said that the airline had changed the tickets to non-refundable. I have since contacted Orbitz, American Airlines, and British Airlines about the tickets, and the problem has not been resolved. On the return flight, I finally received a partial refund (short $43.90) through Orbitz, with no explanation of why it was short, but I have still not received a refund for the outgoing flight. The airlines say that since I bought the tickets from Orbitz, I would need to get the refund from Orbitz, but the agent at Orbitz continues to tell me that the tickets were not refundable.

All of the confirmations I received from Orbitz clearly state that the tickets were refundable. I paid a higher price to get refundable tickets. All I am asking for is that Orbitz refund the tickets they sold me as refundable tickets.
