Just got a new phone, with a new number.  Haven't given the number to anyone except family.  I received an unsolicited call from 312 348-5111 on my new cell phone today (Tuesday 5/25/10) after having received a call on Friday from 425 -562-3215 (this one is a collection agency).  I don't know how they got this number.  Must be trying to contact previous owner.  I see they do this to everyone.  Write you reps, or this will not stop!
