Just wanted to share an update to those having the same problem as I am -
I met with the after-sales supervisor today (she was the one whom I spoke with on the phone prior).
I brought with me the B (she asked that I bring the box as well) and the copy of the original receipt - she didn't really do a thorough inspection but did check my account and the contents of the box.
According to her, they now have a way of testing the bag odor within the store which should only take a day or two, and from there, make a determination whether or not to send the bag off to Paris. While there were zero questions asked (even DH thought it weird that while she wasn't admitting the possibility of a defect outright, she also seemed to be completely not at all surprised by it either). I was not one of the lucky ones who got offered a replacement or store credit on the spot. However, she advised me to send her a list of color preferences in the meanwhile because she thinks the likelihood of me getting the same exact same bag will be tough. She also added that gold, bamboo and vermillion were 3 of the most difficult colors to get.
Will keep everyone posted. I am praying that everything goes smoothly for me!
Good luck! If it makes you feel any better, most members here had to wait for their bags to be shipped to Paris for them to determine if the bag was defective. Afterward, they then had to wait months for a replacement. It is rare in my experience to be offered a replacement on the spot. I hope you don't have to wait too long!! H definitely is aware of the defective bags which smell like true skunk when exposed to the sun, but I am not sure about the ones that smell more "grassy" or like poop. Best wishes for a speedy resolution!!
