Vodacom Insurance added without consent

I have called and spoken to. Agent in vodacom insurance department.to query why i have an insurance fee added to my bill when ,i did not request it, i have asked them for the signed form or voice recording where i agreed to take up this insurance . Besides the phone they have on record is not even a contract phone . Vodacom complaints responds with generic feedback not really of assistance. Shameel Joosub is this how your departments are run. Shocking.
