WRONG PRICING AND BAD ATTITUDE

I HAVE JUST ARRIVED IN MY HOUSE FROM SPAR ORCHARDS IN NELSPRUIT, I WENT TO BUY FEW ITEMS, I CAME ACROSS SEEMINGLY SPECL ON RED APPLES AT THE FRUIT AND VEG SECTION, THERE WAS A BIG PRICING WRITTEN RED APPLES WERE R12.99, WHERE THE BIG PRICE TAG IS SHELF WAS EMPTY, RIGHT AT ITS BOTTOM WERE ALSO RED APPLES 1KG AND THERE WAS NO PRICE , I ASSUMED MAYBE THE R12.99 REFERS TO IT.I TOOK THEM.BY BTHE BAKERY SECTION, BANANA LOAVES HAD R10.99 PRICE BUT A BIG PRICE SAYS R8.99. WHEN I APPROACHED THE TILLS AND SAW THAT PRICES WERE NOT CORRESPONDING, THE CASHIER JUST SAID IGNORE WHAT IS ON THE SHELF THIS ON THE SCREEN (TILLS) IS THE REAL, I ASKED FOR HER SUPERVISOR, SHE SAID SHES RIGHT NEXT TO HER OR AM I LOOKING FOR A WHITE PERSON? THEN THEY CALLED SOME LADY FROM FRUIT AND VEG WHO TOLD ME THAT ITS NOT THE SAME BRAND OF APPLES, I ASKED HER HOW DO YOU EXPECT US TO KNOW IF THERE ARE NO PLU`S, SHE WALKED AWAY, THEN I SAW THAT I WONT GET ANY HELP HERE, WHEN I TRIED TO PAY, THE CASHIER WAS BUSY WITH OTHER CUSTOMER. I STOOD THERE FOR 10 MINUTES IN THE POINT OF SALE, SHE DIDNT OFFER ME A PLASTIC. ON MY RECEIPTS, THE FIRST TRANSACTION WAS DONE AT 18:05 AND THE LAST AT 18:06. IM DISAPPOINTED
