Deducting money without authorization

Sanlam please stop deducting money from my acount cause I have terminated the contract i had cause of poor services I was receiving from your company, I have been patient with you but it seems like this is a game to you. It has been a year now sending me from pillar to post and i am tired of going to bank every month reversing my money. I am being charged all the time when trying to reverse my money at about R50 per transaction. So please RETURN my money and leave my bank account alone. I am happy with the company I joined so leave me in peace.
