Who called from 8137038200

I keep getting called also.....nobody there when I pick up. My rule of thumb is, if I say hi once or twice and nobody acknowledges, it's not a "personal call".....it's something "bad" (solicitor, robo call machine).....I hang up if nobody says something within literally 1-2 secs

Returned  call was told the # had been disconnected

Same response as TADICK.  I said hello twice, no answer.  I hung up within seconds.

They don't seem to care what time they call or how many times. I've gotten to the point I let the answering machine answer for me.

This one shows up on Caller ID as unknown and calls at least one time a day.  The caller never leaves a message.  It's getting to be a pian.
