Telkom - trying in vain to cancel and still receiving bills!

I tried to cancel the unused Telkom home line on my property in South Africa in May 2018. I was told I needed to do this online, not over the phone. I did this online. Nothing. I phoned again, I was told this was entirely possible online. So I did it again. I emailed to contact, I was then told I needed to email a copy of the ID. I did this. I then received a reply email that I needed to do this online. I did this, again. Yesterday I received another Telkom bill. I have tried in vain since May 2019 to cancel this account. I have screenshots of the confirmation, I have emails. yet nothing cancelled. I do not have a south african mobile, I cannot be contacted by phone, especially on a telkom phone I no longer use! I need my phone line cancelled, and reimbursed since May when I first made contact to cancel.
