Really dissatisfied

<p> </p> <p>I have no idea how I can stop FFW value added services from taking my money. I cancelled my policy in August 2016 after I tried to claim and they rejected my claim, I then realised I am paying for a service that I dont need. at the end of every month money is being deducted from my account, every time I call I am told that they are cancelling and that I have never cancelled before, I am spending more money every month contacting them. Am I supposed to go change my bank account or does anyone out there know of a solution? </p>
