Telkom ignores line cancellation requests

It appears to be impossible to cancel an existing land line no longer required with Telkom as there customer service outlets refuse to assist and advise that you have to email a letter of cancellation to: [Email Removed] This I did on the 25th of February 2016 and have sent an additional four (4) requests via email to this email address for which I receive absolutely zero feedback from Telkom - not even a read receipt. I continue however to be billed for a service I no longer require since February 2016 and the online system does not allow cancellations of services. <br> <br> Would you please put me in contact with someone who is able to assist as I am not prepared to continue being billed for a service I have cancelled in accordance with the terms of the Consumer Protection Act. Telkom's continued billing for this service is in violation of the CPA and I expect this to be resolved without further delay.
