Unsure what to do now.

I had my second interview with the school from my previous post. I was super excited and felt it went well enough. They told me I would definitely be receiving a call today since they had to make their final decision today, but I've received no calls today. I've tried calling the person who set up my interview and was my interviewer but went to voicemail after ringing and her school phone goes straight to voice mail. What do I do now? Do I try to call the school this weekend and on monday to find out what happened or is it pretty clear I didn't get the job? I just need to know what to do, cause wehn I get home, I saw the job reposted on k12jobspot.
