BAD ATTITUDE AND DISCRIMANTION

I WENT TO MR PRICE CENTURION MALL ON SATURDAY 14/07/2018,AFTER WAITING ON A LONG QUEUE I WAS TOLD THAT MY SIGNATURE DOESN'T MATCH WITH THE ONE ON THE CARD, AND THE CASHIER WITH HER MANAGER THEY JUST CANCELLED THE TRANSACTION.AND THEY DIDN'T WANNA LISTEN TO ME,AND NOW AM LEFT IN THE DARK I DON'T IF MR PRICE IS TREATING ITS CUSTOMERS LIKE ********* OR THEY JUST DON'T CARE, THE WORST PART IS THE FACT THAT I HAVE BEEN BUYING WITH THE SAME CARD AND SIGNATURE SEVERAL MONTHS AND THEY NEVER TOLD ME ANYTHING ABOUT THE CARD AND SIGNATURE,AND ALL I WANT IS THE ITEM THAT I WAS REFUSED TO PAY WITH MY CARD AND THOSE LADIES ATTITUDE IS VERY ANNOYING TO THE CUSTOMERS AND THEIR ************** TOWARDS BLACK PEOPLE LIKE ME WHO IS BEING TREATED LIKE A ******** WHILE AM PAYING MR PRICE
