Telkom Cancellation Request Ignored

11 months after canceling a service with Telkom I am approached by debt collectors for an outstanding amount as the subscription is still active. The cancellations were done via self service as Telkom instructed me to do, my Telkom product dashboard shows no products or services against my name and I no longer received any invoices.

This is now the 2nd time in 2 years I have been unable to cancel a service with Telkom. It took me 3 months to cancel my LTE account when I moved to fibre. Now I seem unable to get rid of the fibre account.
