Service cancelled from 09/10/2015

I send a request with the completed and signed request for cancellation form that Telkom send me on the 09/10/2015 to both [Email Removed] and [Email Removed] the emails that are on the form. Today on the 06/01/2016 they phone me and says I owe them over R3000.00 because Telkom did not cancel. I am not going to pay money because Telkom *****ed up. You can pay the over R3000.00 that is owed by yourself Telkom and cancel the service back dated from the 09/10/2015 when the cancellation request was send. Contact me, I have all the emails I send to Telkom's cancellation department from the 09/10/2015.
