Unable to cancel MWEB account

I have been trying, unsuccessfully, to cancel my account for months. Despite your website saying you can easily cancel online, the MY PRODUCTS page does not offer any functionality to cancel. Phoning any of the numbers is wasted effort as no calls ever gets answered. Ive sent a message on FB messenger as well and have not received a response. I have cancelled my Telkom line in January of this year already so it is now 7 months that I have been paying for MWEB and not using it. URGENTLY cancel my account!!
