I made a reservation months ago w/ Marriott points at the Four Points Sheraton Singapore Riverview for 12/17 check in.
Reservation was active in my Marriott account.
I did a Suites Night Upgrade and got an confirmation yesterday that my room was upgraded.
Now the reservation doesn't show at all in my account under active or cancelled reservations, and manually searching for it with the confirmation number yields no results.
Anyone have this happen to them? Do I need to call and continue waiting on hold forever to fix this?
