Who called from 8645179540

Getting unwanted calls from 864-517-9540 - don't know who it is or why they would be calling me.  i don't know anyone in South Carolina.

I just got a phone call from the same number 20 minutes a go!  Grrrr...

This number calls me about once a month. Never a message left.

No notes above since September.  He must have taken time off but now is active again.  Got a call from this number 10 minutes ago.  No name, no message.  Just the number in the caller ID and a hang up.

Just got a call on my cell phone from 864-517-9540.  When I answered, there was no one there. I don't know anyone from Greeneville, SC. The phone number ID appeared. no name, no message.
