Telkom hasn't gotten back to me about cancellation

I emailed my cancellation form and ID to Telkom on 10 December 2015, for a cancellation of my Telkom line on 15 January 2016. I received an automated response stating that I would receive a response. I have not received any response to date.<br> <br> Please confirm that my cancellation request will be actioned on 15 Janaury 2016, and that my deposit, in the amount of R700 will be refunded to the account designated in my email.
