We do apologise in advance for any inconvenience caused to you as a GHA member."
What I find shocking is that Discovery is displayed everywhere on Outrigger website, even the logo global hotel alliance on bottom of the Outrigger Koh Samui hotel page !!! I did not expected that answer at all. 
Maybe wait a few days and then send an email back to the hotel saying “upon checking the hotel’s website, I see that your property is now officially a GHA Discovery hotel. Congratulations. I understand from GHA Discovery customer service that because the hotel is now part of the program, my benefits will apply. Thanks, etc”
