Had a negative remark on credit reports XX/XX/XXXX. Determined debt was not mine. Originator was XXXX. they sold this debt to XXXX then it went to XXXX. XX/XX/XXXX collection agency XXXX was notified via XXXX XXXX and XXXX XXXX XXXX that XXXX was in error and I did n't have the account in question. XX/XX/XXXX the same debt is now being pursued by ERC-Enhance Recovery Company. I submitted the info to them in XX/XX/XXXX as per documentation from the XX/XX/XXXX events. Now have negative remarks on credit report from ERC. They never replied after XX/XX/XXXX info faxed to them. Just received another letter stating owe money. They have not provided any information that supports that I have any debt owed. They have falsely reported to the credit agencies and are attempting to collect debt which is not mine.
