I purchased a CHANEL Caviar Quilted Jumbo Single Flap Black from Fashionphile and it took me a while to notice but the tip of the turnlock on this bag has faded from gold to silver and now it drives me nuts and I don't want to carry it any longer.. Since I don't have the receipt and it's older than 5 years I know Chanel will not repair it (I've called and gone in). Is there anything I can do to fix this or somewhere I can take it or would you just sell it back to them? I already got a quote to resell to Fashionphile and it would be a $1100.00 loss from the price I purchased it at. Just looking for advice.. thanks!
