do they retract already posted miles due to duplication?
ok, I got 2 of the "failure to post miles" notices due to duplication ("prizes are limited to one of each prize per household") letters today, except that my miles already posted to my accts. what do they do, go back and retract them? or is it a mistake?
do they go by the email address? or FF number? or name of FF acct? what makes something a "duplicate"?
