Dishonest and misleading Vodacom.

I have had an utterly bad experience from a dishonest and misleading Vodacom. I received a call from Vodacom before black Friday offering me a good deal if I upgrade. I agree. After receiving no response for 2 weeks I call to enquire and get told that the agent was not supposed to offer me the deal and they are investigating. The order then gets abruptly cancelled without any notification to me. A week later I call to cancel my contract. They ask if the can do a deal match. I agree and even email them a similar Telkom deal on the iStore site. 5 days later I enquire about an update and get told someone will call me that day. 2 Days later nothing. When I call them today, I get put on hold and the call gets cut off after about 3 minutes. They are now making it even difficult to cancel my contract.
