Who called from 8607560343

Also called my number but hang up when I answered

I have gotten several from this number - I answer, they hang up.  I Sly Dialed them (267-759-3425) - which allows you to leave a vm without calling them, Sly Dial told me that it is a pre-paid cell phone.

I've gotten calls from this number several times over the last few months with no indication of who this is.

Since I don't recognize the number, I haven't picked it up.  No message has been left...this caller has called before and done the same.

Calls from this number with no one on the line, and if I let it go to the machine, no message left. Frustrating when you are expecting an important call!
