Vodacom funeral cover cancellation delayed

I have been trying to cancel my vodacom funeral cover for 3 months now, and everytime I call the agent tells me that the matter is being escalated and they'll get back to me within few days because my funeral cover is linked to my vodacome phone contract. I'm done aying for that phone contract so I want to know what is the hold up for. The money for the funeral cover has been debited for two months now, while this damn cover is not getting cancelled. No one gives me a rational reason as to why it is so damn hard to cancel that funeral cover or who is it escalated to, because when I call vodacom line they cannot help me as well. So how long should I wait ?
