Cancel my policy please 4th request

I have spoken to a lady on the 6th or 8th of April - explained I wanted to cancel and the reason behind the cancellation - the consultant said that she would like to remove the arrears on the policy for me to continue and also that she would get back to me in regards to the inconsistent debit dates that money gets collected - not once did I agree to continue with the cover. Again I receive messages that my account would be debited. Again I need to contact Discovery. Explain the story again and now I'm being told that I need to give a calendar month notice. I think I have given enough notice and I'm fed-up with the service your consultants render.The man assisting today became ****y when giving him the details and just wanted to get me of the line. He did not want to get a manager to assist and then was placed on hold - he got back and apparently his manager was busy and would call me back in 5 min - I'm still WAITING Discovery????I want recordings of the last conversation where the consultant told me that I need to complete a cancelation letter?I would also like to get information on who to contact to claim arrears back and penalties my bank charged after my requests.
