Debits for a canceled policy

I canceled a policy with assupol 11 days after taking it but they kept on deducting on my account with no success because I stopped the debit order with my bank. 4 months later they are still debiting and when I try calling them to enquire I stay on the line for an hour without being serviced. What happened to the rule of IF PREMIUMS ARE NOT PAID FOR 3 MONTHS THE POLICY LAPSES? Which part of I don't want your policy can't you guys understand?

I WANT MY MONEY BACK!!!!
