Can't cancel Dischem med policy . No contacts supp****.

Hi. I cannot get hold of a contact person to cancel this useless policy on so called medical insurance. My Husband has had this policy for over 18months. Even the pharmacist at your own Dischem told us this insurance is useless. The e mail provided keeps coming back as unmailed as a **** address. Please provide a contact number with a real persons name so we can cancel this policy. A waste of money and our faith in what we thought was a reputable company.
