Hi guys! My auntie bought a small classic flap last july. she's only used it a couple of times but the last time (recently) the stitching came loose and the strap on one side is basically coming apart... She bought it from Wynn Las Vegas but because she does not reside there regularly we are hoping to take it to the nearest Chanel boutique (South Coast Plaza). Do you know what kind of fixes Chanel will offer? i am not sure they will exchange the bag even if she has her receipt since it's several months from when she purchased it...but it is a manufacturing defect... Thanks for any help you might have!
