Points deducted for reward that you never ordered
So I get an email from Marriott Rewards confirming my order for twelve 010 Room Upgrades -5000 points each for a total of -60,000 points. Problem is, I never ordered any rewards. Called the Gold desk and had the rewards canceled but they couldn't tell me how this happened. I'm a little concerned that my account has been compromised, anyone ever had this happen?
