Enhanced Recovery Company , LLC, says that I owe a XXXX bill for {$220.00}. I paid XXXX {$150.00} on XX/XX/XXXX as a " Settled in Full '' Now they are saying and also reporting on my credit report, that I owe an additional {$220.00} and when I called on XX/XX/XXXX, I spoke with XXXX representatives and they are unwilling/unable to assist. I called back in XXXX and disputed it, they said that the documents will be sent to me. I never received them. Called yesterday, they said the documents would be sent and I do n't believe that they will be. 

How can there be XXXX identical {$220.00} bill from ERC representing XXXX? I paid, they are refusing to remove the hit on my credit report. 

Any help would be appreciated.
