The 25 dollars refund is like YMMV things, I have a dozen of tickets cancelled last year mainly between US and Asia, I would say 3-4 times they refund the 25 dollars as well then the rest of just no matter what you say, they just refused, it is really hard to make additional calls for only 25 dollars as it is really painful to call AV, I would just eat these 25 dollars, not really a bit deal, to be honestly.
