Not updating credit profile for paying customer

Good day

Tried to chat to an agent on the Telkom website, but kept waiting for someone to assist. I have had my Telkom Mobile account since last year. I haven't missed a payment. Today when I logged into Transunion, I saw that my credit score has decreased. I phoned them and they told me that it is because Telkom hasn't updated my account over the past three months. Can you kindly update urgently and continue to do so every month so this don't become an issue.
