Ive cancelled my account two months ago but they keep billing me

<p>Im totally disgusted with Telkom.</p> <p> </p> <p>After months of pathetic service and no internet for weeks on end (and many many technicans) I decided to cancel the non existing service. I spoke to agents and requested it be cancelled, i sent a form to cancel it and still im getting billed. Ive sent about 15 emails to their accounts departement an this is my reply "</p> <p>Delivery has failed to these recipients or groups:</p> ********** /> The recipient's mailbox is full and can't accept new messages at this stage. Message therefore not delivered. Please try resending this message later. [Telkom SA SOC Limited. Registration nr : ***]"</p> <p> </p> <p>Is it possible to get service from Telkom in order to cancel teh lack of service from Telkom and stop the billing!!!!!!!!</p>
