Cannot get a policy cancelled

I have been trying to cancel a Gap Cover policy, but have been sent from pillar to post. I know why you are doing it, is to deduct the premium because the "cancellation was too late for the debit order run". I spoke to Sifiso in the Gap Cover department and was promised I would get forms to complete in a few minutes and he would send them immediately. I am STILL waiting. Another delaying tactic. Why can you take a policy online, but you cannot cancel it online? Apparently you need a "paper trail", YET there was nothing requested when I took out the policy. INSURANCE COMPANIES CANNOT BE TRUSTED.
