Sold Policy under false pretense/ policy covering someone unknown to me after giving correct details of person to be covered.

I signed up for a funeral policy in February of 2022 and the funeral policy has been deducting for five months. I gave the details of the person to be coverrd with ID number and date of birth. 5 months later which was July 2022 i met the old mutual agent at my place of work and he told me that I could add my kids to the same policy at no cost. A few days to week later i received an sms from old mutual that i have opened an funeral policy with this same details of the person covered in March and my two kids are covered in this new policy. I then looked into the policy only to discover the main member on the march policy has a totally different details to the one i had covered and this second policy which i signed up for under false pretense was also covered by the policy i signed up for in march 2022. It has been nearly a week I've been calling old mutual and sending emails as i wish to cancel both these policy and to be reimbursed for the money i paid covering a person i do not know. To date no one has called me back ive just beengl given a reference number and no action from their side.
