Dissatisfied by Sanlam/ Sanlam Sky- Unfair treatment

On Friday the 17th/05/2022 I went to Boksburg Offices to cancel the policy no.***6 and received a message for surrendering the policy at 03H08 pm and there after was paid a cashback on the 23rd/05/2022. The policy continued and was hoping that it will stop, then on the 02nd/09/2022 went back to claim all the payments done. I was told that the policy was not stopped, nothing that I did to cancel while I even received the message of confirmation. Another cancellation form was completed and told that they will refund only one month of which they did not. On the 07th and 08th/09/2022 I then called them to explain my dissatisfaction and that they must refund the four months that I paid after I have cancelled the policy but was told that only one month will be paid. Up to today nothing they did as I was told. I want Sanlam to pay the four months i.e. June, July, August and September after I cancelled the policy, they are ignoring me and now they are not even responding after I wrote to their Complains Department on the 10th/10/2022
