paying for cancelled assurance

I cancelled my assurance policy with liberty in August 2015. I was then asked to send my new policy documents for my new policy with momentum. I have sent these only about a dozen times to a dozen home loan consultants. They have loaded endless service requests and closed them but still the librrty assurance keeps going off my home loan account. <br> <br> Its now the 3rd month that Im being billed for a policy I cancelled in August.<br> <br> Is this fair??? Is this right??? Then standard bank wonders why I want to change banks.<br> <br> Totally unacceptable and frustrating from a bank that claims to have thier clients best interest at heart all the time.
