What to do if a scheduled phone call never comes??

So I went in for an interview at a certain chain coffee shop and I feel like I nailed it; can’t imagine doing any better than I did. The store manager said he’d call me at a certain time but it’s been hours since the agreed upon time. He’s called me before at the agreed upon time so I know he is pretty organized. Does this mean I did not get the job or should I call them back the day after? I may be freaking out a bit out of proportion but I really want this job.
