INCORRECT INFORMATION ABOUT PRICING

I CALLED THE STORE AND SPOKE TO ANNA, I ADVISED THAT I AM LOOKING FOR A FRAME WITH HOME WRITTEN ON IT. SHE THEN LOOKED FOR IT AND ADVISED THAT IT IS R299.00 AND ON 50% OFF SO THE FRAME WILL BE R150 ON PROMOTION TILL THE 26/06/2015. MY FRIEND OF MINES ALSO BOUGHT HER FRAME FOR R150.00. THEN SHE PUTS ME HOLD FOR A WHILE AND COMES BACK TO TELL ME THAT SHE WAS NOT THERE THIS WEEKEND AND SHE WAS NOT AWARE THAT THE PROMOTION WAS CANCELLED , DUE TO AN ERROR. I THEN ADVISED WHY DID YOU NOT CONFIRM THAT BEFORE GIVING ME A PRICE, SHE THEN KEEPS QUIET. I ASKED HER AGAIN AND THEN SAME NO ANSWER. I ASKED TO SPEAK TO THE MANAGER ANNIE, SHE ADVISED THAT THE SALES PERSON , ANNA TOLD HER THAT SHE NEVER TELL ME THAT THERE IS A FURTHER 50% PERSENT OFF. I TOLD THEM THAT I HAVE THE CONVERSATION RECORDERED AND I CAN EMAIL IT THROUGH. SHE SAID THERE IS NOTHING SHE CAN DO. I THEN CALLED THE CUSTOMER SERVICE DEPT, SPOKE TO NICOLE, SHE DID HER INVESTIGATION AND CAME BACK TO ME AND CONFERENCED CALL ANNIE TO ME , ANNIE ADVISED THAT SHE SPOKE TO HER AREA MANAGER AND THERE IS NOTHING THEY CAN DO AS THE PROMOTION NOW ENDED ON SUNDAY AND NOT THE 26/06/2015. THE AREA MANAGER COULD HAVE CALLED ME THE CUSTOMER!!!!!
