telkom does not cancel contract and over charges in month it should have been cancelled

<p>I have a telkom smart internet 5GB deal at R219 per month, in April 2016 I requested telkom to cancel this contract on the 24th month (June 2016) I have submitted a cancellation form . In June 2016 I phoned the telkom call centre to confirm if the contact will be cancelled , a call centre agent rep**** they phoned me twice when I asked which number they called she told me a number I have never heard of, now in July I am being billed R513.13 for a R219 contract I have requested to cancel!</p>
