Not getting any service

<p>I have been struggling to cancel a service that I no longer need (and my 2 year contract is over). I have contacted telkom and then they tell me to send a blank email to ********** to send me a form. They never did and then I eventually got the form from Afrihost. I emailed the completed cancellation form on 30 March and still no feedback. I am also still getting invoiced for the service I requested to cancel effective from 1 April 2017. It does not help I contact Telkom or go into the store as they just tell me they cannot help me?? </p>
