Vodafone Live package

Received a billing for vodafone live R150. I have never subscribed to this I have no idea how it works. I phoned and asked a refund and proof that I have subscribed to it i get told I will receive an phone call or sms . Today I received an sms saying all recurring VLive Subscriptions will be cancelled at the end of the subscription period. What on earth ????? This is daylight theft. If one phones and asks for an extension of data there are so many security checks yet this can be added to ones account without approval or even knowledge.
