VERY BAD CUSTOMER SERVICE ????

I HAVE BEEN A LONG STANDING AND LOYAL CUSTOMER OF STANDARD BANK FOR THE PAST 20 YEARS. I HAVE MAINTAINED AN EXCELLENT CREDIT RATING FOR ALL THESE YEARS. THERE HAS BEEN A DISCREPANCY WITH REGARDS TO FORM OF PAYMENT AND I HAVE BEEN THREATENED WITH LEGAL ACTION AS WELL AS HAVING MY CARD SUSPENDED. ALL BECAUSE A PAYMENT OF R500 WAS OUTSTANDING. NO SMS NOR ANY COURTESY CALLS WERE MADE TO INFORM ME OF THIS OUTSTANDING AMOUNT. I HAVE OPTED FOR ALL PAYMENTS DUE TO STANDARD BANK TO BE DEBITED FROM MY ACCOUNT AND CANNOT UNDERSTAND WHY I WAS NOT CONTACTED WITH REGARDS TO THIS OUTSTANDING PAYMENT. I CALLED THE COMPLAINTS RESOLUTION CENTRE AND WAS MET WITH A DON'T CARE A DAME ATTITUDE TOWARDS MY COMPLAINT. I INTEND ON MOVING MY BUSINESS TO ANOTHER BANK, AS STANDARD BANK CLEARLY DO NOT VALUE THERE CUSTOMERS.
