<human>: Story: I am a summer student worker at a lumber mill in town. I get paid a ton of money to do the most boring work I've ever had to do. Also, because I am a summer student I am on call, so as much sleep as possible is a necessity. Anyway, for the past 2 weekends I've gotten prank calls from an unknown number. It's not that big of a deal because I don't (normally) get called in on weekends. Last night I received a call after I had gone to sleep, but luckily I knew which shift I was working so my phone was on silent. However if they begin to consistently call me during the week it could cause me issues, and I was wondering if there was anything I could do? I was thinking of threatening legal action but I seriously doubt that prank calling even counts as anything. Changing my number isn't really an option because I think they know me personally, I just don't recognize their voice. So help?
