I received a generic email today from AA refunds stating that I was not entitled to a refund of the $75 I spent along with 15,000 miles for a mileage upgrade seat for a flight that was cancelled by AA due to Covid 19. The miles were refunded immediately after one phone call more than a week ago but now this. Can anyone explain why AA would say "We're sorry, our research indicates the fee was charged correctly, and no refund is due." I thought all associated fees and taxes were to be refunded for a flight that was cancelled by the airline.
