Difficulty in cancelling my ADSL contract after 24 months

<p>I have an ADSL contract with Telkom which reached its 24 month on 10th June 2017. I have emailed a cancellation letter to Telkom 3 weeks ago and they say someone will contact me within 21 days but todate i have not received any call from cancellation The problem is you can only commnunicate with the cancellation department when they call you not the other way round. This put me in a difficlut position as promotions from other service providers ends month end on June 2017. My request to telkom is to please cancell my contract as i have been your loyal customer over the last 24 months.</p>
