No assistance in cancelling Telkom ASDL account number ***

We sold our house in George, Western Cape at the end of last year (2016) to move back to Cape Town. On the 4th January 2017 I emailed a signed and complete scanned cancellation document to the designated Telkom email address. I received an automated reply mail from said address, informing me that my cancellation request has been received and that it will be dealt with and that someone would contact me in the event of any further required information or action on my part.

I paid up my account in February thinking that, that would be the last of the invoices. However since then I have received an invoice every month.

I have contacted the cancellation department telephonically no fewer than three times, each time being asked to forward said emails, which I have dutifully done, never to receive any feedback or acknowledgement of receiving the information. And every month I get another invoice. I am at my wits end about what to do as I get no reply from Telkom.
