I cancelled my policy in December 2024

I cancelled my policy in December 2024. Reason being financial difficulties. I am currently unemployed and since my premium did not go off my account from December 2024, I assumed that the policy was truly canceled.. my premium went off my account on the 7th May 2025. The only money that my brother had sent in my account for me to buy food was debited by these rogues. When I called them I was told that a cancelation agent will call me on the 7th and the money is still with the bank and will be reversed, I called again later only to be told by another agent that my next debit is now canceled and that the current debit was tracking my account since April and as soon as funds hit my account, the debit went off.. How do you make poor people suffer for your tracking of debit order like a predator stalking it's prey.. I want my money back now
