Who called from 7812730820

Got my first call today from this # @ 9:46am.  A minute before, I got a call from an unknown #, then a minute after the 781 #, then another call from an unknown #.  3 calls--all to my cell phone.

Im in Houston with Verizon Cell Phone and recieved call at 2:59pm ...went straight to voicemail no message was left and when I called back it said "Im sorry but the service you are trying to reach is unavailable" Obviously a scam just wanna know how they got my phone number

got a call from this number this afternoon, no message, and i live in miami.

got a call this afternoon. since the area code looks strange to me, I didn't pick up. right jumped to search on the site, and may consider it as a stalker number.
