BILLING MESS

I am having endless issues with Telkom and their billing. I have requested cancellation of my contract on the 30th of August. They failed to do their work and my contract was not cancelled. I had to send the cancellation form in again more than once. I even had to go back to the store. The contract was only cancelled on the 27th of October. They debited my account for the full amount and now they only want to refund me for 28-30 of October. WHY must I pay because your staff is not able to do their work?? Cancellation case: ***6<br> Case for refund: ***5
