Unable to cancel contract - no feedback

<p>I had my landline number ported to a different service provider and then sent Telkom notification of my cancellation, with all the required documentation. It's been over a month now and no one has gotten back to me regarding the cancellation of services. I phoned telkom only to find out that the call centre does not deal with cancellations and only an email address is available for cancellations, this being the email address I used initially. I have since emailed weekly requesting assistance but no one has yet gotten back to me.</p> <p>Appalling service and no wonder I'm cancelling services with them . </p>
