DEBIT ORDERS FIASCO

I HAD A ISSUE WITH TELKOM ABOUT A MONTH AGO ABOUT MY DEBIT ORDERS THAT WAS NOT GOING OF MY ACCOUNT. I PERSONALLY WENT INTO THE STORE AT GREENSTONE MALL AND CHANGE THE DEBIT ORDER DATE FROM THE 25TH OF EACH MONTH TO THE 30TH OF EACH MONTH. NOT FOR MY CONVENIENCE I MIGHT ADD. THE END OF JUNE CAME AND WENT AND MY DEBIT ORDER DID NOT GO OFF MY BANK ACCOUNT. HOWEVER THIS MORNING THEY TRIED TO TAKE OFF A DOUBLE DEBIT ORDER WHERE I ONLY OWE THEM R374.50 AS PER THE SMS SEND FROM THEM EVERY MONTH.
