Well its not showing up on either mine or my wifes accounts so we are obviously excluded.

I used Topcashback all the time to make our Hilton bookings.
We have been loyal to Hilton for a decade not booking with any other chain.

Obviously it leaves a bad taste in the mouth when Hilton chooses who is valid for their targeted promotions because I am never targeted.
Now I am also being excluded for Topcashback bookings as well it takes things to a new low level of nonsense.
