I purchased an Amtrak ticket partially with an Amtrak gift card. The train cancelled so I called to see if I could get a voucher (knowing that the Amtrak gift card payment would cause complications). The agent refunded it instead by accident. When I received the refund receipt, it showed the refund going back to two credit cards, not one credit card, and one gift card. I have no idea who the other credit card belongs to. I did not receive any sort of refund back to the gift card.
The agent apologized and told me to call the Refunds department when they were open to have this fixed.

When I called and was transferred to refunds, they flat out told me that it wasn't their problem and that federal law requires the refund be sent back to the initial payment methods (which they did not do!) and that I should call my bank, and then hung up on me.

I sent an email to customer relations. I'm going to wait a week before I go up the ladder and email people further up the chain.

Is there anything else I can do, or am I going to be out my fifty bucks? My Congresspeople are useless as I found out when I contacted them when Amtrak's charged a higher points redemption rate than stated on their website.
