What days does the Admissions Office respond to emails?

I attended the Experience NC State event on Friday but I didn’t have the chance to grab an excuse note from the registration table. I was told to email the Admissions Office to get a PDF, but they haven’t replied even 2 days later. I need it preferably by Monday but Tuesday at the latest or else my absence will be counted as unexcused. Should I resend my email? Does the Office respond on weekends at all?
