I've gotten 2 calls from this number within days of one another. Tonight, I received one at 10:30 pm.  I gave Google voice so I let it go to voicemail. No message. I turned around and called the number back using my Google Voive number and a woman picked up and said hello, hello.

Funny thing was when I hung up for a split second, I saw on my screen another number....as if I had called another number. Then this number showed again.

I don't know who this is but I'm going to find out.
