The Collection Company : AFNIXXXX XXXX XXXX XXXX XXXX, XXXX XXXX XXXX, IL XXXXTelephone : XXXX calling and sending collection bills to my house for a debt they said I owe to XXXX They are collecting {$4400.00}. 
I do not owe any money to XXXX XXXX XXXX, I have never had business with XXXX XXXX XXXX, and I want that AFNI company to stop their attends for collection. 
I recently returned a bill to AFNI and told then that I do not owe money to XXXX XXXX XXXX, and to fix the delinquency report they submitted to the Credit Report Companies ( XXXX ). 

The situation is that around XXXX 2013, someone made business with XXXX XXXX XXXX and probably under my name. Then around XXXX 2013 a debt collector made a delinquency report to the Credit Report Companies ( XXXX, etc ). I called the collector company and told that I do not owe any money to XXXX XXXX XXXX and I have never done business with then. 
I requested then to undo the delinquency report. But they kept the collection account and then transferred to another Collector Company which is this XXXX AFNI. 
See attached last bill for collection.
