Paid up and bureaus not updated

I had an outstanding account with Nimble, which I settled and paid in full. i received the paid up letter and asked if the bureaus could please be updated accordingly. I was told this would happen with the normal data submission to the bureaus. As of now the bureau has still not been updated. I sent an email and asked again, i was told it was done and I should check directly with the bureau, which I did. The data submitted for my account was 30.04.2024, and no new information was sent through. When I ask nimble to assist, they direct me to the bureau and close off my call. They are not assisting me to have my information updated correctly, even though when I paid the loan off, they said they would ensure the bureaus are updated timeously. Now that I have paid my loan, they refuse to assist further
