Not impressed with the network

<p>I am very angry with Vodacom. My line and phone has been blacklisted for no reason. On the 29th September my phone suddenly lost the network , I called Vodacom and I was informed that my phone was blocked by someone in the Vodacom shop at 20:17 which was after hours. This is the second time it's happening and I am extremely inconvenienced. I would like this matter to be resolved if not I will pursue legal action. My account is up to date and I want to cancel my contract </p>
