This phone number is for Enhanced Recovery Services. I owe a bill to AT&T from 2009 I thought I had paid but it may have slipped through the cracks when I got cancer. They are actually rather nice when you talk to them but they are legit unfortunately, they just call my number for two other people that are not me. Phone numbers are recycled and they remove the incorrect people when I tell them. Trust me, I do not like bill collectors but mainly because I am a debtor, lol. You should just not answer so they have no way of knowing if they are contacting the right person and if its a cell phone, block them so they can't call you. The ios7 now has a block feature and if you have blackberry I used Mr. Number and loved it and there are a plethora of apps for android. Good luck everyone.
