I have bought plane tickets for 4 passengers from Expedia to fly from Singapore to Thailand via Thai Lion Air(subsidiary of APG Airlines). 2 Days after purchasing the tickets, I called Thai Lion Air for a change of flight for 2 of the passengers. The tickets are now separated into 2 sets of 2. First pair flies on 01 Dec while the second pair flies on 03 Dec. I did the necessary payment and confirmed that transaction has gone through my credit card. Confirmation and receipt was e-mailed to me for all tickets(2 sets of itinerary).
On 01 Dec, the 2 passengers were denied check-in as the Airline system reflects no-go because payment was not made. The pair was forced to purchase a new set of tickets which cost twice as much as the old tickets. I contacted the airline and was informed that their system shows no-show and they could not proceed with the refund. The airport ticketing staff issued us a log which indicates everything that happened since the purchase to the day of flight but their system back at the HQ shows otherwise.
On 03 Dec, the last 2 passengers were able to board the plane without hiccups.
I have contacted my credit card company and Expedia regarding this and both parties stated that all payments are cleared. I have lodged an e-mail complaint attaching every piece of supporting documents showing that the passengers showed up but the airline is not responding.
I want a refund for the new tickets which cost twice as much. What can I do to get the money back? It felt like the airline is deliberately pulling this stunt to scam money.
