IHG Rewards Club run a Cyber Week Sale that have an offer of boosting Bonus Points Package points by 50% (read more here).
Seems that IHG initially made a mistake and gave 500% bonus instead of the advertised one (read more here) and has now started to claw back those points.
You can access IHG Rewards Club here.
Here’s what posted to members account:
It was only matter of time before IHG was going to remove these incorrectly posted points from members’ accounts. Not sure how someone managed to make an error of programming 500% bonus instead of 50% one though?
