Cancelation of contract

I am currently jobless. My Mtn contract was due for upgrade 11 Oct 2015 so I decided to cancel my contract as I dont have sufficiant fund anymore. Went to my branch at Mall of the North to cancwl it they said it cant be done instore so they phoned 808 for me. I talked to a guy there he helped me and said I should receive a email confirming my contract is cancelled. Its saturday already no email received. I also paid the outstanding amount instore last monday because they said it cant be canceled without an outstanding amount. This morning i phoned to twll them i have'nt received any emailing concerning my contracts cancelation and also they checked the systwm telling me that the contract is still active! Now what the hell did the guy help me with at the call centre?? What the hell did i pay for?? I refuse to pay another debit order because i requested this should be cancelled before the new month starts so it was not wich means ANOTHER debit order i going to go off because of some ashole not doing their jobs!!! I got news for you i have incificient funds!! Pls cancel this contract!! For the 3rd time. Vodacom is much faster and in control in helping their customers in the same situa
