Vodacom Bad Service

Did a premature contract cancellation in May this year with Vodacom, now in October I start receiving calls daily from them telling me I owe them. This after subjecting me to my number being disconnected from the network for two weeks due to their incompetence, instead of transferring my number to prepaid they instead cancelled my number completely from the radar. Went to several Voda shops for assistance and was only assisted there after several attempts with their call center without any joy. I will never Ever in future have any other dealings with Vodacom. The next time I decide to purchase another phone, it will definately be with another network. Vodacom doesn't value or even recognize their client loyalty. Just yesterday, I now receive an email from them with a letter of demand. I really give up on Vodacom, they have no shame.
