I received a promotion in the mail in late August for a shortened night requirement to maintain Platinum till 2019. On the post card, it said that it would only take 20 more nights to renew platinum. I got 38 more nights since the date of the postcard but Marriott won't honor the promotion and claim that I didn't meet terms and conditions that weren't disclosed anywhere on the postcard. Did anyone else have problems with this promotion? I've attached the postcard.
