incorrectly debited

the agent that called me for a policy did not get authorization form me to process the policy. spoke to three different people and i told all off them that i do not want the cover and they still debit my account. Collin was the first agent i spoke to that took my details then a lady that i cannot remember her name and she said she will send me the letter to confirm my request and then call me back to process the policy. then a guy phoned me to help cancel my old policy and i told him that i am still waiting for the letter before i proceed and he said he will get the agent to call me. Collin called me again and he said he cannot send me the letter and i told him to cancel. all is clearly stated on the recordings three times and they still debited my account. to cancel i must now wait for them to follow there procedures to get the money returned when they did not follow the procedures in the first place
