Business ProfileforPhilippine Airlines

Me and my wife had booked a round trip from *********** to ******* on Philippine Airlines leaving on March 13, 2024 and returning back on March 23, 2024 ( Record locater 44IR8I). We paid $8499.00 for the round trip ticket. The day of our return flight on March 23, 2024 sometimes in the middle of the night we received an email from Philippine airlines with a title 'Simple Re- Accommodation'. There was no call or text message. We woke up at 7 am and saw the email. Buried in this email was the flight cancellation notification from ****** to ** on March 23. They rebooked us 5 days later on March 28 from ******. They wanted us to stay 5 more days in ******!! We frantically called PAL with our **************** travel agent, were on hold for two hours without any resolution. At that point, we bought another last minute ticket to LA (one way) for the same day on a different airline, spending $8000 on the tickets. After that AmEx send PAL notice to refund our money, no response from them initially. Two weeks later, **** called with me on hold to PAL, finally they came on line and processed the request for refund. I received email from PAL that I will receive the refund ( unclear amount ) for the flight cancellation, BUT it may take up to 3 billing cycles. In my opinion, this is totally unacceptable that an airline which services US customers, for an unscheduled cancellation they are dragging their feet to refund the money. They received my money right away but now I have to wait months to get my money back, and no idea how much they will refund back, if they ever do. I humbly request that BBB help me resolve this issue with PAL at the earliest, rather than waiting upto 3 billing cycles. We should get the full amount of new ticket we had to purchase last minute, amount of $8000.00. PAL customer service is atrocious. Thank you for your assistance in this matter ********************************
