ISTORE IS VERY UNFAIR SERIOUSLY. WONT TAKE BACK NEW UNUSED EARFONES

WENT TO THE ISTORE IN SANDTON CITY AND WAS ASKED FOR A PAIF OF EARFONES. WASNT ASKED FOR WHAT FONE AND I PAID AND WENT MY WAY NOT KNOWING THE IPHONE EARFONES ARE DIFFERENT, WHEN I GOT TO WORK I OPENED THE EARFONES ONLY TO FIND THAT THEY GAVE ME WRONG EARFONES AND WHEN I CALLED THE CONTACT CENTRE I WAS TOLD I CANT RETURN THE EARFONES BECAUSE OF HYGIEN REASONS AND I HAVENT EVEN USED THE EARFONES! HOW IS IT MY PROBLEM SINCE THE SALES GUY GAVE ME WRONG EARFONES? THIS IS SO UNFAIR... AM TRULY DISSAPPINTED OF THE SERVICE I GOT FROM ISTORE.
