un approved policy/insurance charges on my account

Jet stores assigned 4 of their own insurances with out my consent and agreement and they have been charging these on my account. I enquired about them asked them to be closed, I was assured that they have been closed and in the following month I was not debited. Just after a month the charges were debited again< I went to enquire and I was told that it is the head office that asssigns insurance policies to their customers and the polocies were re acticated again after I have asked them to be de ac tivated. these policies are a Personal Funeral Plan, Legal Plan, Hospital plan and personal accident plan. <br> If hello peter could assist me with stopping these charges and if possible getting my refund back as I have not agreed to pay for these insurances.
