Telkom refuses to refund after I cancelled my account 4 months ago

<p>I cancelled my Telkom adsl service for February 2016. The debit order continued to deduct from my account every month until June 2016. I spoke to a person at the call centre and she said that my account will show a positive balance and then it will be refunded. Thus far I still dont get any answers. It is not acceptable for Telkom to deduct hard earned money from my account when I have cancelled it months ago</p>
