I booked an award flight from RGN-PGV and then return IAD-RGN for late last year in December to go home for Christmas. However plans changed and I called to cancel the return leg, have the the taxes and fees refunded and miles recredited (which I did less than 21 days before the first flight). I told the rep what I wanted to do, and she did it no problem and assured me that I'd get my refund and the miles would be back in my account shortly. I paid a $75 fee for this as well.

Now I've been waiting for 2.5 months and still nothing. I tried calling customer service but they told me to file a refund request online. So I tried filing a refund request but I've gotten no response.

Should I just call the Mileage Plus number directly and talk to them? Do you think the rep just modified the ticket, charged the $75 to change it within 21 days, and didn't refund anything? What can I do to get them to fix this up?
