Standard bank Auto payment, Thank you

I cannot believe my eyes! I wake up in the morning to see that standard bank does an auto payment of R4070 from my cheque account without my permission! No notice of the amount to be paid nothing this was just taken from my account without my permission which is literally the money for my petrol, groceries and other expenses , how is it right for a bank to do this without your permission!! This is ridiculous standard bank you cannot do this to people who have made plans to use their own funds for specific purposes. Just utterly appalled by how these banks actually take control of your hard earned money!
