Policy Cancellation Run Around

The worst customer service ever. We cancelled my father's policy in November, and they told us they would deduct for the last time at the end of the month. But they deducted again end of December. I have since requested for the call recording where my father apparently said the policy must not be cancelled. When I call in, its either the consultants can't hear me or they give attitude. I did the cancellation and follow ups on behalf of my father as he has given me the permission as he is old age. But Elias, their consultant, is so rude. He told me that I am not a police and he shouldn't even be talking to me about the policy.
