Someone from the " XXXX, '' a debt collection agency, put a negative entry -- out of the blue -- on my Experian credit report in the amount of {$85.00} for account number # XXXX. XXXX bought this debt from XXXX I know this because the report lists XXXX as the original creditor. At any rate, I disputed this with Experian and they claimed the dispute was valid. This is not impossible as I have never had any credit/loan/debt/services or anything from XXXX. XXXX has no information to prove that this debt is valid ; they only provided Experian with my identifying information. Experian did not investigate, thoroughly. Also, XXXX can not provide me or Experian an original bill with date, times, and amounts where I took out an {$85.00} loan/credit/service with XXXX or XXXX for that matter. The last time I dealt with XXXX was over XXXX years ago when I closed an account owing ABSOLUTELY NOTHING. I would like this egregious negative claim removed from my credit report.
