Clientele Funeral Cancellation

My Name is Karl Barnes, I have numerous times requested on email to clientele to cancel my policy, nothing to date. I even made phone calls and I will be asked to leave a message as someone will call. However all falls on deaf ears. I want my policy cancelled and I cant even stop it from the bank as the bank refers me back to these people. Please assist as I have exhausted the last option by requesting for them to contact me as someone who is seeking policy. When the woman calls she could hear me in the beginning, when I mentioned cancellation she pretended not to hear me. I also need my debit orders paid back for the last two months.
