Who called from 2190000000

Received a call from this number every day this week, I picked up today and no one was there and disconnected right away....getting old fast!

Do you know who it is?

This person started calling yesterday and I ignored it. I did answer it today and then he hung up after I inquired who he was. Hmmm.... Perhaps it is some political yahoo.

Keeps calling, third time today.  They don't say anything. I'm getting pretty mad.

I got a call from this number 3 times yesterday and 5 times today. i pick up and there is no sound. and the number cannot be called back...weird.
