ADSL LINE CANCELATION NOT CANCELLED SINCE 2016 - NO RESPONSE

I cancelled a Telkom ADSL line in 2016- since then I have spoken to numerous persons who have always promised that it would be cancelled- I have a e mail communication of about 16 emails - directly sent o the persons I spoke to - without any replies - The last communication was another follow up email on the 9th September 2018. To date it still has not been cancelled and has cost me R7000 PLUS ALREADY- My view a money making **** of Telkom , as this seems the norm of what I have picked up.
