Capital Accounts, LLC Debt collection department,

I do not know Attempts to collect debt not owed Debt is not yours Florida

My credit report reflects a charge for something that is not mine. I have tried to call the company involved, they refuse to help even though the socials and birth date do not match. They said I have to get in touch with the collection agency, which I have and they refuse to help me as well. I contact the credit bureau, all three of them and filed a dispute 3 times with experian, have so with - and -? The file remains on my report and again this is NOT mine? For some reason they are refusing to remove what is not mine and ruining my credit. Again in - alone I have disputed this charge with - three times. Called the collection agency. Called the company originally involved.
