Designed to make it hard to cancel

I have been trying for over a month to get a fax line and a golden number cancelled as my company can no longer afford to pay this. I have sent many emails to all the email addresses linked to telkom that I could find. I have called them on numerous occasions, each time they tell me that I have to cancel it by creating a profile online and then linking the existing accounts to my profile and then cancelling the services. The system does not allow me to link the accounts to my profile and nobody can help me to cancel these services.

This system was designed with the intention to make the customer experience better, but it fails miserably at this. I will block the monthly debit order and refuse to pay anything further until this issue is resolved
