TAKING DEBIT ORDERS AGAINST CLIENTS WISHES

AFTER I HAVE CANCELLED AN INSURANCE EXPLAINING TO THEM THAT I DO HAVE AN EXISTING INSURANCE, THEY STILL TOOK OFF THE INSTALLEMENT. I HAVE REQUESTED A REFUND AND THEY ARE NOT EVEN BOTHERING TO CALL BACK OR REPLY ON THE EMAILS. THIS IS VERY POOR SERVICE. AND TO TOP IT ALL OFF, I HAVEN'T EVEN REQUESTED AN INSURANCE WITH THEM.
