I just had an issue trying to do a points booking (only limited hotels participating in this). Provided all information, then the reservation failed, but the points were still taken from my account. Called customer service… told this functionality does not work for any hotels and has not worked “for some time”. Supposedly my points will reappear in “a couple of days”.
Update: Was able to get a supervisor to open a ticket and the points were added back within the hour. Reservation agents cannot make points bookings as that functionality currently not working. I was able to make the reservation on second attempt.
