Interview

I had an interview this past Thursday for a crew position and the manager interviewing me said he had two other people and would get back to me by Friday night. Well Friday passes and I didn't hear anything back, so today I called the place to see if they had made a decision and the employee that answered the phone told me his boss wasn't there and to call back in a few hours. About 3 ish hours later I call back and (I think) the same person answers the phone, he asks for my name and I hear shuffling for about 2 minutes till he comes back and tells me they aren't hiring and he doesn't know why an interview was scheduled... I'm just so confused. I turned 16 recently and I've been applying for months and this is only the second interview I've gotten so I really needed this job, should I call again tomorrow and ask for a manager or just let it go?
