No reply on service cancelation

I requested cancellation of my account on January 6th 2016 with the required documentation by email. I received a confirmation email stating that an agent will contact me in 48 to 72 hours. There was no follow up.<br> <br> I called the Telkom helpline on January 11 2016 and was informed that no one can assist me with cancellations and that I was to send another email to the service cancellation email which I did on January 11 2016 and re-attached my documentation. I once again received an email stating that I would be contacted in 48 to 72 hours which did not occur.<br> <br> How do I get a response confirming receipt of documents and when my account will be cancelled?
