No response from Vodacom regarding activation of unwanted so called free insurance

<p>Vodacom promised me that they will contact me regarding the offer of free insurance that I am being billed for. I declined all insurance. And then received a message saying my screen insurance has been activated. I phoned Vodacom and the consultant assured me that this is a FREE offer accompanying my upgrade! Invoice arrives and I am billed for this insurance. I dont want to pay for something I never asked for and especially not something that after I queried it, I was assured is FREE! I totally feel this is unacceptable!</p>
