I got a call too.  Didn't answer.   Sara, they probably find out some 3 digit cell phone prefixes in a given area code, when use a program to automatically generate and increment the last 4 numbers dial like crazy.

I received a call from them at 136 pm today. Didn't answer

I Find out that scams get our numbers form websites like facebook, twitter, emails and others social websites! It sucks!!!

I get at least 5 Calls a day from Scams!!! and it sucks!!!

called me two times today i didn't answer
