EGARS ROBS POOR PEOPLE

I BOUGHT ITEMS ON THE 01/12/2019 AND THE CASHIER CALCULATED THE SAME ITEM TWICE OVERCHARGING ME BY R90.00 AND SO I PAID IN GOOD FAITH ONLY TO REALISE WHEN I NEED TO CHANGE THE ITEM FOR SIZE TO SEE THIS OVERSIGHT. I WAS VERY DISTURBED AND UPSET SO I WENT TO THE STORE TO COMPLAIN TO THE MANGER TO WHICH HIS RESONSE WAS SORRY! THATS IT! HOW DO YOU ROB POOR PEAOPLE AND THINK ITS OK! I GAVE BACK THE ITEMS BUT I WILL NEVER SHOP THERE AGAIN. IAM SO HURT AND I EVEN CRIED AT THE STORE BECAUSE MY DAUGHTER REALLY LIKED THE ITEMS I BOUGHT NOW SHE IS WITHOUT CHRISMAS CLOTHES. HOW MANY MORE OTHER PEOPLE DID THEY DO THIS TO????
