Cant replace my product because of price differenc

So my JBL Synchros s200a headphones came apart. I bought this product on the 25th of November 2014 when it was on special.<br> <br> Now takealot has the black one but they dont want to replace my product because of the price difference.<br> <br> Either the supplier needs to give me a new pair or a black pair as I cannot buy another pair for R499.<br> <br> Im really upset. I support takealot almost every month and the least you guys can do is replace it for me. I asked for these earphones to be returned to me as I already ordered foam tips from america. This alone cost me R1000 with delivery. I cannot cancel this.<br> <br> Im not a chancer so please look into this as I am really upset. Its still within the warranty period. I don't want my money back!!!
