Per the discord, you can contact CS and they may be able to address this if you attempted to use it on 3/7. Maybe they'll be kind and give you extra time.. I'm wondering if they just didn't want a March Madness promo code and SORRY promo code running together.
Keep in mind, HD is already one of the lowest grossing games for WIS because every coach gets 1.50 for just playing.. many good coaches play for free. I don't blame them for not wanting to make the game even cheaper for an incident they had no control over (not that those are HD's feelings). I'm not even sure why they have the 1.50 reward set in place.
