Bad customer service - Vodacom

The customer service from Vodacom is non existent. I have used all avenues to try and get hold of Vodacom to rectify the issue with content services being added to my account without my consent! I have responded "no" to their consent messages. I have deactivated the subscription via the self service option. Yet I was billed for this. I've tried to contact their Customer Care Department on various occasions, they are always experiencing “high call volumes”.

I then visited a Vodacom shop who could get hold of Vodacom's Customer Care Department. The sales consultant confirmed that I have been unsubscribed. I received an SMS a day later from Vodacom to inform me that the subscription has been reactivated as per my request. I responded "no"' but is 100% certain that Vodacom activated this service on my account. I also e-mailed their Customer Care Department to try and establish why this is happening. NO RESPONSE!!!!!!!
