i got mine waived on first attempt for all 3 cards.
you do not need to wait for the anniversary for each card to get a waiver.
just call to waive all your cards, then they will place an instruction for all your cards
then once the annual fee gets charged at different times for different cards, there will be an instant waiver triggered to minus off the same amount.

works perfectly.

i guess you did not read the fine print eh
if you're an old time customer, here's a hint
do not go for advertised promos - they are mostly for new customers
call them and ask them for cash discounts
