And the plot thickens... I sent them an email complaining that I booked in December, and asking if I could get the points as a courtesy. To which they responded:
Thank you for contacting Wyndham RewardsŪ.
Please accept my apologies for the confusion.
Qualifying stays that were booked prior to January 18, 2018 will still be honored for the promotion.
Please allow 6 to 8 weeks for any applicable bonus points to be credited to your account after your qualifying stay has been credited.
For more information about Wyndham Rewards Terms & Conditions, please visit the website at
www.wyndhamrewards.com.
If we can be of any further assistance, please let us know.
So, if this latest email is correct, it looks like I will get the bonus points after all. (but given all the confusion so far, who knows what will actually happen...)
