AFNI, INC. Illegal re age on credit report Bloomington, Illinois

I accessed my husbands credit report today and discovered an item being reported by AFNI, INC.  The item is an old cell phone account that should be reporting as opened in 2007 and last paid in 2008 but by some strange magic Afni is reporting it as opened 5-2010. The balance is also considerably higher than what was owed to the original creditor.
 
Good news Afni! I am a debt collector. You may be able to pull this kind of garbage on the average citizen who doesn't know any better but it won't fly with me.  I'm extremely excited to use my knowledge of collections to teach a lesson to an unethical agency.

Will post updates on progress.
