Sunlam joined policies without my knowledge

I have never been so frustrated like this..On the 17/04/2024 I have emailed Sunlam my cancellation form for the policies that their funeral advisor joined for me without my knowledge.The reason for cancelation its because we didnt agree with premium amount and he added people that are already covered because he was commision at my expense. Last month they have paid refund for the premiums but even this month those funeral policies keep on deducting...Sunlam please advise me what is the process of cancelling your policies,it seems like feeling in a cancelation form its not working..I dont afford your premiums..I DEMAND MY REFUND AND CANCEL ALL YOUR POLICIES...
