I say take these phone numbers and start typing them in to places that'll call to solicit them back !!
I have a theory about all of these unsolicited calls. Mine started after I was erouneusly put into collection for a bill that wasn't mine; Now days when they think you owe the money all you get is an automated place to call so you can make the payment.   So you write your letters, you do whatever you need to do to try to rectify the situation. Eventually start to ignore the company; Curtis Rash is most notorious for this.  My theory is that "Curtis Rash"
actually sells your name, information,everything about you to people who solicit and Robo Call?  Prior to the collection issue I never had any of these problems .  It sucks because I pay 140 bucks a month for my celland 60 bucks a month for LANDline,   I stopped answering them both .  Of course if I did a money is affecting my ability to earn you idiots ! ( it's been Curtis Rash )
