Vodacom Account Settled but they don't want to update the credit bureaus

My Vodacom account was handed over to Burnard Raaff & Associates. On the 27/05/2024 I made a settlement amount of R6,467.00 and received a paid in full letter from the collection company Burnard Raaff & Associates on the 04/06/2024, I sent the same letter on the same date to *** and to this day I still have not received any response and when I check the credit bureaus my Vodacom account is still showing a balance owed. Vodacom please can you'll update my Vodacom account as paid and close my account.
