Contract Cancellation

I sent through the cancellation form to [Email Removed] on 5 February 2016 and I still have not received any confirmation that the contract has been cancelled.The contract expiration date was 31/03/2016. <br> I was first called by a lady who wanted to assist me with cancelling the wrong contract (my WIFI). I do not know how this happened as the number is clearly specified on the cancellation form. I notified the lady of this and she said she would notify the Mobile division to assist me with the cancellation. I did not receive any call from the Mobile Department, that is when I contacted customer care and opened a case, case no. is ***9.<br> I unfortunately missed a call from Telkom Mobile, I was notified of this when I contacted customer care after some time had passed without hearing from Telkom Mobile on the cancellation. No voice message or contact number was left by the person who contacted me. I have contacted customer care several times to get assistance with this cancellation, all they do is send emails to the Retentions Department which go unanswered. I would like this contract cancelled ASAP and do not want to continue to be billed for this contract. Please assist.
