MiWay REFUSAL TO TERMINATE SERVICES

I recently cancelled my insurance and policy with MiWay some months back. I clearly communicated with them to cut all services attached to my name. Upon communication with them, they sent a written communication confirmation regarding that. They stopped some of the services and funny enough, they are still deducting regardless of their agreement! I've sent them emails addressing this problem and nothing is being done about this! I can't keep on going to the bank to reverse these transactions month in month out for their foul play!
