Accidental no call no show

Alright so I’m 16, I work a cashier job at stop n shop, and I’ve never had any issues. I’m part time, I work Sundays, Tuesday’s, Thursdays, Fridays, 18 hours a week. I have explicitly stated the days I’m unable to work, and Saturday specifically. My parents are divorced and my dad lives two hours away, and I have to have visitation with him. I basically never check Saturday on my schedule, since it’s the last day and I know I’m unavailable ALWAYS on that day. Only, today I realized that I had been scheduled 12-6 for a Saturday, as I am two hours away in the city. I had gotten a call much earlier in the day, but hadn’t picked up due to the fact my phone had been off and left at my dad’s while we were out. By now, the service desk is closed and I have no direct way to contact my department head, nor my managers. It will be considered a no call no show, and while I’ve looked over the packet I was given on work guidelines when I was hired, it gives no strict guidelines for a no call no show, only to call out if you can’t make it to work. I’m really worried, will my situation be understood if I communicate properly when I return to work tomorrow? I know it’s only a first job, but I’m really worried since not many other places near me are hiring. (Lmk if this was the wrong flair, I wasn’t sure if it was appropriate)
