Dishonest clientele team

I called in November to cancel my policy. End of November the debit order went off, I then reversed it. I received a call in December regarding the reversal and I told the consultant that I am no longer interested in the policy. December the debit order went off again. I called in and I was told to send a letter for cancellation. I sent that letter and to my surprise month end of January the debit order went through again. I called again because both December and January debit orders were not able to be reversed. The consultant said she will cancel the policy, however the previous conversations don't reflect on her side even the email that I sent it's not there. She said she will send the request to her superiors for investigation. The only thing that Clientele told me via email was that they concluded that I am not due for a refund for Dec and Jan as there is no proof that I cancelled the policy before. I forwarded the email to them again as proof. They say there's nothing for them to do. I am very disappointed and angry with clientele legal department for being so dishonest with me as the customer. I don't think I will ever do business or take any policy related to clientele.
