So they gave me 642 miles which supposedely means $1284.00 spent. From September 1-30 (when the purchases cleared), I spent $1542 in swipes (signatures) and $2.15 in PIN purchases. None in which equals 642 miles. I write all my purchases down on a spreadsheet and their wasnt alot to keep track of. I tried to add up ANY purchases that would equal $1284 and i couldnt. So weird... FWIW, I last used the card on 9/26 (cleared on 9/27) for $844.64. And there were no AS purchases. Anyone have a clue?
