I upgraded my contract with Vodacom about a month ago, I wasn't happy with the device and then I returned it in less than 7days I've been phoning Vodacom for the past few weeks and every time they have different stories about my contract cancellation. I just want them to cancel my contract so that I can switch networks and look for better services
