For some reasons, I cannot create or modify any award reservations from my Marriott account. Any attempts always end up with the error message "Please try again. If the problem persists, you may call 1-888-236-2427 from within the USA or Canada. If you are calling from a location outside of this area, please consult our worldwide reservation directory for the appropriate number."
When I called, the agent was also clueless. Any ideas what happen and how to fix it?
