Poor service when canceling

I called to cancel my car insurance in november and was told it has been cancelled but will take place beginning of december.... i was ok with that and now they still deducting money for the insurance. I called in now to cancel again and was 10 mins on a call and only spoke to one guy who transfered me to the cancelation department. I then spoke to waseem who did not want me to speak to his supervisor and dropped the call WHILE I WAS ASKING FOR A SUPERVISOR ..... TOTALLY UNPROFESSIONAL don't know what training he got. Why is it so difficult to cancel your stuff in sa ***
