Per the thread here: http://forums.xbox.com/xbox_forums/xbox_rewards_support/f/29/t/1600564.aspx I have been asked to reach out to billing to get my membership fixed. I suspect that the "promotion" component is a result of the unwinding of the family pass, as I have not used a promotion recently nor was there any issue with the rewards program before the changes occured.
Are you able to address this please per the solution in the associated post?
If not, what is the best way to get in touch with someone who can.
I am not getting my rewards at the moment and would very much like to resume them.
