As a holder of the Visa Marriott rewards card, I was awarded an e-certificate for a free night stay at any Level 1-5 hotel. My e-certificate isn't available now. My account activity history says my e-certificate was cancelled. I did upgrade to the Premier Plus card a few months ago, but I don't know why that would cause me to lose my certificate. Anyone know what is going on and how I can get my night back? Thanks.
