I pulled my credit report In XXXX 2015, and it showed a collection agency " Common wealth financial system/ NE Credit collection '' reported to XXXX and XXXX an account in the amount of {$750.00}. I disputed this account with XXXX on XXXX XXXX, 2015 advising the account was not mine and on XXXX XXXX, 2015 the investigation was completed, advising proof of the debt was provided. I mailed a dispute directly to the entity on XXXX XXXX, 2015, advising the derogatory report be removed, and to provide validity of the debt/ account if the derogatory reporting is not removed. This dispute was received by the entity on XXXX XXXX, 2015 and as of today XXXX XXXX, 2015 the derogatory report is still on my credit and I am yet to receive a response from them validating the account.
