Debit order continuing after cancelation >2 years ago

I have now been trying to cancel my MiWayLife (MiLittleLife) policies since 21 April 2017. NO ONE at the call centre can help me - no department can help me (they keep transferring me to other departments between life and personal) and no one has a record on the system of my policies. It's been over two years that I've been trying to cancel, full mail trail exists. So, according to the call centre there is no knowledge of my policies, yet my debit orders keep going off. This is theft.
