Bad Service from Vodacom.

What a bad services I have been receiving from Vodacom... I am totally not happy with the service Vodacom has been giving me, Some of the consultants that are working for vodacom does not really deserve to be working with customers as they are helping us but what they do is lie to us and at the end of the day we are the only ones that suffer the consequences. I have been calling in to vodacom for my contract to be cancel but it was not canceled now I am the one who must pay for the airtime? Like really now! Vodacom must really check the people they hire before they loss their customers, because some of the customer care consultants will really cost vodacom their customers. The thing is that the consultants just because they want you to upgrade and you don't want to they mess everything up for you, which is not right. I am not happy with Vodacom.
