Telkom SUCKS

Hi I have cancelled my Internet and Land-line on the 1st of March. I send a email like they requested me to do. Still I receive invoices monthly that I need to pay, and the amount keeps on growing. Calling the call center does not help they keep on telling me they will come back to me. They want me to pay for a service I am not using. Account ********** 05 Its the worst thing to cancel something at Telkom.
