Ok, if it doesn't show for your room type then it is not available for your room. I think I read that if you do see this discount online you will have to book it online. Meaning that calling it in will not work, probably because it is a glitch. It would work for me if I called it in as I have the pin code that matches the discount. But this has to be a glitch for people who did not receive the pin code but are able to book it online regardless, right?
