Removing on credit bureaus

Paid up account With Unifi Loans, I had two accounts. Since last month, on September 19, 2025 all of my accounts have been fully paid. I was assured that the credit bureau will update my credit record. Unifi hasn't kept their word as of yet. I’ve been calling them for almost a month now my credit score keeps on dropping because they don’t want to update on their side I don’t know what to do anymore I have paid up letters they sent to me
