Who called from 5105427487

Sang into phone, "We're almost ready", asked for unknown person. Have received a lot of hang ups, etc. from (510) this week.

I don't know this number, but o see three Facebook pages trying to sell me something showing up on this page. They must be using fb to get contact info and phone number. VERY BAD CALLER IF TRUE AND NO COINCIDENCE.

When did this site begin showing ads, especially ones intruding onto my fb page? LOOKS like a hacker to me.

Call from 510-542-7487 at 7:25pm from Berkeley.  I picked up on the third ring and a female voice said"I can't stand you" and hung up.  It sounded like a teenager. I did not recognize the voice.

Keeps calling, does not leave message.
