Vodacom Insurance *****ing money

Firstly, I recently found out that Vodacom added an Iphone 7 insurance onto my contract in 2017 which I never agreed to. I would like to please find out where I signed and agreed to this insurance as I do not even own an IPhone.

Secondly, when I found out about the insurance on my name, I phoned in August to cancel the insurance. We in the middle of October and you have done nothing. It is still on my contract and still deducting every month. Please take this insurance off my name and I want a refund of my payments made. You guys are *****ing a client money and not adhering to the customer act.

I spoke to a lady named Gray this morning 14 October who stated that the cancelation did not go through and I have to wait 30 days for a refund to show. Please explain to me how you can just ignore a client request and just continue taking money on my expense. Why do I as the client need to be inconvenienced. I want this sorted by tomorrow.
