Job Interview ‼️❓

So I applied to work as a barista on my college’s campus. (We have one Starbucks in the student union and another in the library)

I applied about a week ago and a few days later I got a call informing me that they’d like to have an interview but I will not be able to work until August (which is fine because I live in a completely different state)

I was told on Tuesday that they would like to have a phone interview which I agreed to.

Fast forward to today, my interview was supposed to be at 11:30 and now it is 11:59. They have not called yet.

What should I do? I know I should call them but I’m not sure when. The person interviewing me is also not the same person who informed me that I’d have an interview. Help!
