I got this call , Saturday at 6:45 on my home phone and my cell phone ans so did my friends....nobody at the end of the line

I answered and it was a spanish lady offering long distance. She wouldn't respond to anything i said so it may have been an automated message. It came up in my caller ID as "predictivo"

I got three phone calls, 18h07, 18h39 and 19h31, as soon as I answer they hang up.

Got this call twice already. First time I missed it; they left me a message wich says to call them back (automated message); second time they hung up on me.
