Please cancel my contract!

Since January 11th 2018 I have been trying to cancel my Telkom contract. I have emailed all the docs for cancellation and whenever i contact Telkom i am told that the cancellation department does not take calls. Furthermore no one in the contact centre can assist me as they dont know what is happening with my request. To add to this the debit order is still going off every month. I am extremely frustrated and disappointed at the lack of customer service and feedback. I submitted requests online, via email and have called and it is now 11 months and no one can provide any feedback. This is my last attempt at getting some answers. I am begging that someone please assist with cancelling the whole Smart Home Basic package; the numbers are ********** ; ********** ; ********** . I have a list of every agent i have spoken to and the email trail of no feedback from them. Please assist urgently!!!
