As an update to my attempt to expedite my match:
Emailed them and contacted them via social media on Friday.
- No response to email yet.
- Social media responded 3 days later that "It could take 7 to 10 business days."
- As others mentioned before, the in-person rewards desk couldn't do anything.
So the moral seems to be: start early and don't procrastinate.
It's weird that according to blogs, it was an instant process a few years ago, but now matching either way takes more than a week. I guess one program updated its system and the connection between them was never reestablished.
