Five missed calls when I got home.  All from this number.  No message left even though my answering machine specifically tells callers to leave a message.  Kind of fishy.  Lefty (guy that owns the bar) he seems to think these types of calls are scams or sales calls.  I don't know about all that.  Now Whipper (Vietnam vet sits at the end of the bar, keeps to himself mostly), he seems to think these calls have to do with the NSA or CIA.  He's got some kind of conspiracy theory on the subject.  Actually lots of subject, but also this one specifically.  He doesn't elaborate to much on these things.  Just kind of makes a statement here and there in the middle of others conversations.  Kind of annoying really. Guy can sip whiskey all day long and it never seems to have an effect on him.  Like I say, "Got 5 calls from the same number on my caller ID when I got home".  Whipper will say, "CIA checking your schedule.  Don't answer.  No one is there anyway.  Answered/missed calls feed the computer".  Then he sips his whiskey. I wasn't even talking to you Whipper!  So, there's that.  Not sure it helps.  

I've gotten a couple calls from this number, but I never answer, and they never leave a message.

Have called me about 5 times in the last couple days. Finally answere, and it was a recording, apparently from General Electric security systems. I told "him" that I am a renter, and it hung up on me.

Has called me two times within 10 min and they aren't even open

Keeps calling me.
