Cancellation is impossible

I have been trying to cancel my Telkom mobile account for months. With absolutely no success. I tried phoning the call centre, which said I must go to my nearest Telkom store. I went to the nearest Telkom store, stood in the line for 30+ minutes, only to be told that they cannot do it in store, I have to do it online. They gave me the steps on how to register. After struggling to register, because your system take forever to sent through the OTP, I linked my account. When I go to my Dashboard, there are multiple accounts. None of them the one I linked. I do not have those devises or numbers. There is also no place on the Selfservice dashboard to do cancellations. I tried to chat with Telkom online, while I was logged in. I am still waiting for one of your friendly consultants to reply. You are very quick to call when I refuse to make payment for something that I do not want anymore, but you have never tried to assist in the matter of cancellation.
