Experian Credit Reporting Complaint

Experian Credit reporting department,

Incorrect information on credit report Information is not mine California

Experian has a trade that does not belong to me with 'unknown ' status. This trade is not reported by any of the other bureaus ( which I was able to access via - ). They have made it literally impossible for me to contact them to ask for resolution through any real time channel ( phone or web ) and the only option they are giving is to dispute via mail which can take up to 30 days. I am applying for a mortgage pre-approval and do n't have that much time.
