Refund a ticket on 8/18, didn't see the money back to the AE I used. Call Cathay. They claimed it's refunded on 8/23 on their record. Called AE. No evidence of such refund. Called Cathay both Reservation and MPO, both said they can't help any more than saying their record shows refund happened on 8/23. I asked them to investigate and they refused, adamant that what their record shows is proof enough, and the problem is on AE side. Called AE, didn't have any record Cathay attempted a refund.

Anything more I can do about this?
