Contract has expired BUT Telkom still wants me to fill a form to cancel the expired contract!. Otherwise they keep billing

<p>My contract with Telkom mobile expired on the 01/12/2015.</p> <p>Telkom mobile kept debiting my account even though i was not even using the device.</p> <p>I'm now being told that Telkom will not be re-imbursing me of all the money they have taken from me post the contract ceasing to exist.</p> <p>Telkom wants me to go to their store, complete a form telling them to stop debiting my account and send it back to them.</p> <p>When a contract expires, it ceases to exist. Therefore if Telkom is an honourable company they will pay back the extra money they have taken from me for the last 15 months.</p> <p>In addition to this issue the Telkom mobile number 081180 can only be dialled from a Telkom device, i cannot use any other number to get hold of them. </p>
