Upset Customer, bad service from Telkom Cancellations department

This is the second review! I have sent a cancellation form to Telkom's cancellations department in January, we are now in March, I have had no feedback, and can not seem to get hold of anyone that is able to help me! Maybe is I cancell my debit order I will get a reaction, and due to non Payment I will be blacklisted for something that is not my fault!
