Credit report

Good day. I am very disappointed in TransUnion for not closing two loan accounts that was already paid up in February. Management of the company has sent you several emails to ask you to close the two accounts. I sent an email myself, with the paid up letter asking for the accounts to be closed but received feedback that I must log a dispute. Why must I log a dispute? It is not my responsibility to ensure that my accounts get updated CORRECTLY on my credit report. It is TransUnion's responsibility. As a result I am not able to get vehicle finance or any other credit. It has been 8 months, this is honestly ridiculous. Please do your work.
