Vodacom cancellation line is a joke

We are trying to cancel our Vodacom contracts. Both my husband and I contacted Vodacom separately on their 082 number and waited 15 minutes in a queue, when the call was answered it was immediately disconnected and we were put into a queue to give feedback on the service. My husband did this 4 times with the same result. We cannot get through to a consultant to cancel. I have read several reports from other people who have had the same experience...some people have left the country and their accounts are still active, after settling them. Poor show Vodacom. Please contact me *** so I can cancel.
