Anderson Fin Network/Bloom AFNI, Inc. Why do I have a debt from them! Bloomington, Illinois

I was just checking my credit, because I was not approved for a Lowe's card and this debt came up. It is from a place that only has a post office box address and the company is AFNI, Inc. (Anderson Fin Netwrok/Bloom). It says the account was opened in 5/2009 and reported 6/2009...as a utility debt. I tried to get some form of contact to this company, but only the p.o. box address came as the result. I will say that I did grow up in Illinois, but not Bloomington, and what strikes me as odd, is why is there a utility bill from that 2009 date when I have been in Oklahoma since July 1st of 2002? This debt is said to be a little over $2,000 and that is an outrage. I am not sure what I am suppose to do, but I am NOT paying this bill. I did not have anything of the utility sort, or anything for that matter from Illinois. I am outraged that this is making my credit so bad and it is not something I even opened. And, to say the least, it is not even under my current name, it is my maiden name, which was also changed in 2002. WHy was this account able to be opened in my maiden name in 2009? Who is not checking into identifications thoroughly and what kind of utility would cost that much of only one months of being used? How do i find out more information on this?
