Some company posted a account on credit report that is not mines. They never even sent me a bill stating debt. But after i disputed they updated account and sent me attached letter.But company still has not provided me information on what the debt is. The letter does not even give me any type of ACCOUNT INFO. 

Account XXXX Bank XXXX, this account is not mines and this bank never sent me any information regarding this bill. I do n't know what this is.
