If in fact it is only one account you have open and they show two active accounts that are being reported then you should dispute it. In one account shows as transferred or sold then that account is not treated as active.
This is the first time this debt was ever on my credit report. The original creditor debt was from 2005.
The original creditor debt was never reported to any bureaus. I did not receive any mail/phone calls that I had an amount due, ever.
