No service no payment, Telkom!

Dear Telkom. When I cancelled your landline and adsl service it meant that I would also stop paying for the service that you do not provide anymore. That means you cannot keep on sending invoices for things you do not deliver, and you cannot threaten to take me to court of I do not pay. You have no humans that customers can communicate with and your service is non-existent. You were not concerned when I left, please understand that no customers means no income.
