Made a costly mistake. I had my wife apply for the US Airways card right before they discontinued applications, she also had a US Airways card from a prior application. I got the statement with the annual fee but didn't realize that it was for the new card, thought it was for the old card. Had my wife call and she had the card downgraded to the Arrival. Now I just realized that I made a mistake as to which card it was. Is there anything I can do at this point to get the 50,000 miles?? Can I undo the change, still never received the Arrival card in the mail. Any recourse?
