MYLIFEDIR orders

First I wanna thank standard bank. You have been able to help me to reverse these **** debit orders with Ref MYLIFEDIR***x although sometime they deduct when I dont have funds and bank charge me R115. Please STD Bank make a way to Stop or block these debid Orders I was told at bank it cant be done because they use different debit order everytime. My account is deducted with amount ranging frm 89 to 99 frm same mylifedir for 5 to 7 times a month. I am even thinking of moving away frm STD Bank
