Who called from 3102794625

Ok, I got this on my cellphone, and I returned the call. It says press one for english and so on. Then asks me to put in my number and 4 digit pin. Whats up with that?

I got a call from this too, about an hour and a half after cindy.
It appears to be an intl calling card access number.  Someone using
such a card (or spoofing the number) is calling us...no way to
return the call...

Oh, forgot to say:
The calling card is "PINGO" (Pingo.com) and the
local access number the caller used is in Beverly Hills, CA.

I got a call too-- I wonder if we all got anything in common, or if it is just random...

Received a call from our calling service with no voice message attached.  We're a family owned villa rental in the Bahamas.  Someone's up to no good.
