I am an AT&T customer currently and have never been with Cingular wireless. I recieved a collection bill in the mail from AFNI stating that I had an outstanding debt of $80.50 from Cingular wireless. It gave account numbers and everything. I contact AT&T since they bought Cingular and they varified that there is no outstanding issues with my acccount. I found this site when I was trying to figure out who AFNI was and thought I would add my 2 cents. AT&T has been great and has their fraud department looking into this. I will let you know how it all turns out, but in the mean time if you are a AT&T (formerly Cingular) customer and you get a bill from AFNI, DO NOT PAY IT and contact AT&T immediately.
