TransUnion Credit Reporting Complaint

TransUnion Credit reporting department,

Credit monitoring or identity protection Billing dispute Kentucky

I just realized that - - - - is showing up on my credit report as an outstanding debt in the amount of $1500.00. I have no way of getting in contact with this company but this account was settled in full approximately 6 years ago. I would like to have this removed from my credit report as soon as possible and have my scores updated.
