Non Renewal and Cancelation of Policy

Good Day, I have cancelled my policy with Elixi Medical Insurance sold to me by Talksure and they are still debiting my account. The policy is renewable every year, they sent me a email stating they are going to renew without me confirming and I rep**** to that email and I also sent an additional email to an address found on their documents as there is no clear cancelation email you can use, stating that I do not agree to the renewal of the policy as I do not require these services any longer and the changes to the policy are not conducive of what I require. I am not happy these deductions have been taken which is higher than what I signed for previous year and also the fact that they sent an email to renew and did not call me to see if I wanted to continue with the policy. I would like a full refund of my monies for January subs and February subs especially since I sent through the cancelation.
