Debt collection — Security Credit Services, LLC (NC)

Debt is not yours. Security Credit Svcs recently reported a {$1400.00} collection account on my credit report. They are stating that the original creditor is a company called XXXX XXXX. I have never heard of this company, much less had an account with them. Needless to say, I have made Security Credit Svcs aware of this, but they refuse to take it off of my report. When I last spoke with their reps, they said I should dispute the account with XXXX, XXXX, and XXXX XXXX. They said that if the account was not mine, it would be deleted. Well, I did that ; and the account is still reporting on my credit file.
