insurance

an insurance policy has been added on my jet account without my knowledge, I've been calling since April to cancel the policies and I've made it clear to the service consultant that I've never joined any policy with Edcon except for the account alone, now charges are being generated in my account and was told that i have to pay for the incurred charges because I've cancelled the policy in the middle of the month, and as per company rule i have to pay for the incurred charges, i told her that it is not my fault that the insurance has been added i want those charges reversed and she further said that the person who added the policy will not get paid but that does not help me with anything because charges are still being generated.
