CANCELLATION OF CONTRACT

Spent over after 2hrs trying to call vodacom customer service, going to voda world to request for assistance regarding my cancellation of my contract and settling the bill so that i can close it off. I had been redirected numerous times to different department regarding my request, worse part was the TOBI option that will only assist with the number calling and not the number you'd like assistance one. Could I kindly get assistance please. I want to settle my contract and close it off.
