Early debit

My debit order date is set for the 25 th of each month as stated in my contract when i app**** for my lone and not any day before then, if the 25 th falls over a weekend it diverts to the day thereafter as you do every month, but this month you debit my account on the 15 th December. when i called i was told that Standard Bank decided to do it earlier and that sms's was sent out to inform us, what a load of lies as i did not receive any sms to inform me. When my wife went to do shopping today she could not pay because you decided you will debit my account today instead of the actual date, you wasted her time and petrol and who is going to compensate us for a waste of petrol. If i,for example, dont pay my account on date you will call a 100 time's and threaten me with legal action but you do as you please!! " I DONT CARE IF IT IS DECEMBER AND WANT TO DEBIT EARLY ,STICK TO THE AGREEMENT WHICH WAS SIGNED. I HAVE NO FUND AVAILABLE THANKS TO STANDARD BANK, REMEMBER NOT EVERYONE GETS PAID EARLY IN DECEMBER.
