CANCELLATION OF INSURANCE

I've requested for insurance that was loaded on my account to be cancelled on 25 February 2019. After i didn't get any feedback on email ********** and there is no answer at the number ********** , i posted on this Facebook page, and still the feedback was that i need to be patient because they are extremely busy. it is almost a month now and no call or feedback has been received. I went to the Vodacom shop in Menlyn just to be told the only way to cancel this is by sending an email to above mentioned email address and calling that number. I DID NOT REQUEST THIS INSURANCE. I do not want to pay for this insurance one more month and I want a refund for the months paid, as AGAIN i never requested this and have other device and laptop insurance
