Vocacom service sacks and its agents are useless.

Vodacom called to offer me and upgrade and I told the agent instead I want to close the data contract. Later in the month an invoice came, huh! I follow up with another call and same promised is made, came invoice billed again and I followed up again and I was told when the cancelled it they've already gave me the data. Mind you the cancellation was done on my follow up call. When I refused to pay and asked them to fix this, they charged me penalties and blocked my phone. When I called I was sent from pillar to post, even now no one has helped me. I guess they have enough clients, I'm not even a storm in a teacup. Their service sacks and they are all useless. I wish the was an office I could go to instead of talking to clueless people over the phone.
