Missy that is a horrible day.
Strongly suggest you consider re-applying for the position. Whoever they hired didnt work out, and perhaps they have no way of knowing if you're still available. Maybe they even tossed away your materials and thus cannot contact you. Just write in and tell them frankly you're still interested. What's to lose? I was a second choice hire at my firm and now i've been a partner for 10 years. Good luck!
