TransUnion Credit Reporting Complaint

TransUnion Credit reporting department,

Credit reporting company's investigation Problem with statement of dispute

I sent a dispute letter to the bureaus ( -, -, and Trans Union ) this past - 2015 requesting that they remove a - debt of $4000.00 that does not belong to me. They never removed the debt, but stated that it would remain in my credit reports. I investigated this debt and Representative - ID # : -/Branch # : - at - confirmed on - -, 2015 that they have no record of this debt in their system with my name, social security, nor address. Please, investigate and find out why the bureaus are not investigating debts properly and doing the job that they are responsible for ; which is resolving disputes as accurately as they can. Your attention to this matter would be greatly appreciated.
