Cannot Cancel a Vodacom contract

Multiple times sent mails via the Customer Care email, [Email Removed] automated replies received with reference numbers in some instances. No reply to my queries regarding contract cancellations what so ever. Also attempted to phone the cancellation line with no success multiple times. Calls were even made by Vodashop East Rand Mall to the cancellation line with no success. I have multiple contracts with Vodacom and have always paid them via debit orders. Need to cancel some of the contracts as they come to an end. I am not even in South Africa any more and still paying! Seems like I just have to cancel the debit orders and forget about Vodacom all together. In addition, also tried to communicate to the so call chat lines. Only Sales Chat line is active and Sales people apparently cannot transfer to cancellations department. Chats were dropped very quickly.
