Telkom has no response to cancellations

I submitted a service cancellation form of my Land line as I no longer live there and do not require it to be moved. The submission was done on 30 March 2016 to the relevant email address- [Email Removed]<br> <br> They have not responded at all and when I call Telkom, I wait no less then 25min before I can speak to someone and all they say is, you must email your request and that's it. No progress tracking, no sms, no emails and not even a call. They just do nothing after that. You dont even get any reference number from them.<br> <br> Telkom is beyond frustrating! no. 1 with the slowest service ever and the worst part is that one cannot do anything about it. If you can avoid using telkom, do your best!
