Vodacom- cancellation request difficulty

I tried to cancel a data contract. Got cut off twice during the conversation with no call back. Attempted a 3rd time and got through to an agent Sile Aube who initially seemed to be helpful. But then everything changed. Despite begging her to cancel the contract she went on and on about why I NEED the contract. I am within my rights to cancel and have absolutely no clause that prevents me from cancelling. I had to explain to her over and over why I wanted the contract canceled and she JUST WOULDNT LISTEN!! Eventually had to provide additional PERSONAL detail to try to convince HER why I want the contract cancelled!am absolutely appalled by the service received. An absolute infringement on my right! If this is the strategy Vodacom teaches their agents to retain business then you will be losing clients quicker than you anticipated. We have several personal as well a business contracts and spend tens of thousands of rands each month and have been with Vodacom from the very start cellphones was first made available. Im more than happy to provide you the details so you can verify this fact. The experience received today has changed my view completely and will be looking to move our business elsewhere. Disgusted!
