*****ulent Account linked on my profile.

I've had account with Telkom for so long. Suddenly when I log onto my Telkom app, there is a number that I do not know. I went to a Telkom Kiosk and was told the number was RICA'd using my ID number. I asked when, and I could not be given an answer. I called client care and was assisted by Nkululeko, who gave me the worst service, I kept asking him questions but all that matter to him was conveying that I should call a number that he had provided in order for the number to be canceled. I ended up asking him to put me through to the survey because Hes service was just nonsense. I need answers, why is there a number that I dont know linked to my profile, if I can see the person's account, how certain should I be that they cant see my details? Who Rica'd the Sim card? And Nkululeko says the number was already canceled 2023 in August, who canceled the number and why is still on my profile? Please sort this out.
