I had a past due balance from an apartment Complex called XXXX XXXX which was sent to Hunter Warfield, a collection agency. I spoke with XXXX XXXX back in XX/XX/XXXX who said that my balance was {$570.00}, but was willing to settle for {$220.00}. I was unable to do that as I originally planned. I called the agency back today & spoke with XXXX XXXX who now says that my balance is {$580.00}. I asked why and he said that they charge interest and that they 've had the account since XX/XX/XXXX. When I .looked at paperwork from XXXX XXXX, my balance was {$520.00}.
