Reaching out to the FT community for advice

I bought an Air France ticket via Orbitz. Shortly thereafter, there was a schedule change of just over 4 hours.

Called Orbitz, they said that Air France schedule change rules stipulate that there needs to be a minimum 5 hour change for them to consider refunds.

Called Air France directly, a sympathetic agent understood my concern, agreed to a waiver (said she would put in a note on the reservation), but I had to go back to Orbitz to get the ticket cancelled and refunded, then write back to Air France via their website, to complete the refund request process.

Did it all.

Got emails from Air France saying they were not responsible for the refund. Expedia (parent company of Orbitz) was responsible.

Called Orbitz again.
They say that the 5 hour schedule change rule applies. No refunds are possible. A kind lady spent an hour or more on the phone with me speaking to various Air France departments. All of them (apparently) refused to help.

Do I have another alternative in trying to get my money refunded?

Air France has offered a credit. But this is worthless to me... as I have no other travel plans in the months ahead where I can use this credit.
