Having the same issue - Orig reservation booked thru SPG @ 24K points (72K post-integration) - Rebooked 8/18 @ 70K to gain 2K points. The agent who did this seem confused, so I waited for two days to call since my 72K points were still not refunded from the cancellation. The second agent I called said things were a mess and it could be up to the beginning of next month before we see the points refunded. I hope this is not a sign of things to come for a once-great program. I used to get points refunded instantaneously. Hopefully, Marriott will get this straightened out soon.
