Taking money out of my Account without my Authorization

Where do I start... Honestly Platinum Life, I am truly annoyed by the gazillion phone calls I receive on a daily basis. I was promised documents will be emailed to me, and once satisfied with the policy I sign and authorize. I NEVER RECEIVED A DOCUMENT!!!! YET YOU PEOPLE TAKE MONEY OUT OF MY ACCOUNT!!!! I stopped the debit order, Received an sms from Platinum life that my bank informed them that I stopped the debit order... BUT GUESS WHAT YOU DEBITED MY ACCOUNT THIS MONTH AGAIN WITHOUT MY CONSENT!!!! I DID NOT AUTHORIZE ANYTHING!!!! PLEASE CANCEL THIS POLICY AND STOP HARASSING ME... I DO NOT WANT THE POLICY AND I DO NOT WANT ANY FREE GIFTS! I WANT THIS SORTED IMMEDIATELY!
