Cancellation of telkom mobile contract

On the 03/12/2015 I emailed [Email Removed] with the request to cancel my contract which has already reached it the 24th month of the contract. I received a response from Charlene Mncube say I should fill out the Contract and Service form and send it off to [Email Removed] which I did. I waited for some kind of response from the cancellations department, I then contacted Telkom on the 28/12/2015 via Facebook as it was nearing the end of the month. They probably forward the message to the retention department with to regards to my query... The retention department responded back that I should again fill out that form and now attach as well my ID... this ****ed me off. I wanted my account to be cancelled in December already as I was billed for that month R660 odd... later in Jan, I was invoiced R466 which I was liable to pay. It is now once again near the end of the month and I have not received any communication after I filled out that stupid form twice. All I want is that contract to be cancelled how hard is that? Please note I will not pay any more money to you guys, try and invoice me for Feb...
