Telkom cancelations

I have been trying since end of April 2021 to cancel my Telkom business line as I took a new package with them. The consultant said they would cancel. Yet I have been paying for 2 packages every month. I have tried calling cancelation department but to no success. I try the numbers they give but it doesn't go through. I even phoned billing they said they can't help. This is unbelievable because when you want to upgrade or new contract it's simple but to cancel its not possible.
