Satrix system repeat purchase error!!

On a day I purchased Satrix 40 ETF for almost R 200,000 and their system repeated the SAME PURCHASE FOR EXACTLY THE SAME PURCHASE FOR SATRIX 40 ETF which I find completely unacceptable! On the very same day it repeated TWO PURCHASES FOR EXACTLY THE SAME SAME PURCHASE AMOUNT FOR SATRIX MSCI WHICH I FIND BIZARRE AND UN-ACCEPTBLE!!!!!!!!!!!
