Insurance not cancelled after months and months....

On 22 July 2019 an insurance policy with Vodacom was cancelled. Firstly we did not select to get insurance. But its fine, we did not check our invoices properly. So when we noticed the policy we called immediately to cancel. Until today 6 November 2019 nothing has been done. The payment for the policy continues to deduct. We have phoned several times and nothing is being done about this. We have to pay for a service that we do not want. Please cancel this immediately and refund the money deducted for this policy for August, September and October. Why does everything with Vodacom have to be delayed and complicated. Unbelievable that you can continue to deduct our hard earned money for nothing. And I refuse to wait months to get a refund, it must be done in this month. Not my problem you guys are clearly *********** to deliver any customer service. Please give us a reason one time to rate your company more than 1 star.
