Vodacom Funeral Policy

I took Vodacom Funeral policy few months ago via telephone, I haven't received the policy documents or the policy number as yet. Yesterday, they called me again selling me the same policy that I thought it was active already, but unfortunately I am not on their system but there are taking my money from my account for the policy every month. I am not happy at all, here I am thinking that I am already covered, but no Vodacom is taking my money for nothing. Yesterday they said they will call me after 10 minutes, even now I am still waiting,
