Who called from 2132102314

They called while I was in a night class a few hours ago but left no voicemail. My phone says it's from L.A. Not long after I received a call from another number in P.A. that did the same thing.

Just got one 2 minutes ago on my cell. 2 rings, then a hangup. ID says it's from LA. Assume it's robocall. I just don't answer any number I don't recognize.

Yeah I got the phone call when I was in class and it said from LA California so Idk what that was about

Just received a call from that number on my cell. It rang once, then hung up. I used reverse phone number to check the number.

Just received a call from the same number as everyone else. At the top of this page there is an ad for Amsterdam pens, I received one of those in the mail the other day for my business. Assuming maybe that might have something to do with the call, maybe.
