HOLLARD Bad service

I took out a funeral insurance with Hollard in March 2021. The person I insured unfortunately passed away in May before the policy matured. I called HOLLARD to inform them about this so that they can cancel my policy and pay me the 2 months premiums as it was stipulated in their contract. I spoke to the official who assisted me with the policy but until this day 17 months later, the insurance is still debiting. So I want my 17 premiums because I did not cause the delay. I don’t understand why they are not cancelling my insurance like I have requested
