Attempting to cancel a Telkom account

I have been attempting to cancel my account since August 2017. There are records of my raising objections and I have not paid the monthly account. At some stage I managed to get the debit order cancelled but even month I receive an account. About 2 months ago I received phone call asking why I wished to cancel the service. The following month I received an account for R26. I was not sure what it was for but paid in the hopes that this would be the end of it. I have now just received another account starting anew with an amount of R217 owing. How is this ever going to be stopped. I am appealing for your assistance. I no longer even have the telephone line. I will find the reference number of the confirmation of cancellation should you require it
