I went through their feedback and saw they bought this same bag under a month ago, same receipts etc...
I'd asked questions prior to this transaction and was told they had simply stored it since new, and it looks like it did when it was brand new....they had all original receipts etc and were selling because she has a black one already.
so I've just emailed the link to when they purchased and asked how could they insist that the odour didn't exist due to their well ventilated closet when they had only had it a month? and that I would like to send this back for a refund...
I specifically asked if the bag had any odours!
and this was the reply:
"I received your email about returning the LV Mahina. I must
inform you that my return policy is only "guaranteed to
authenticity" and nothing else. The bag was new as described
and I did not have any issue with smells. I purchased the bag for
my wife, however she wanted a lighter color, hence the reason
for reselling it. She bought the white and black, therefore did
not want to keep the "Gris" color. I am extremely sorry, however
I will not accept a return of the bag. You asked many questions
and I answer each and every one before shipping the bag to you.
Thank you for your understanding."
The bag still smells musty, this is so unfair.... I don't know, I'm thinking I should perhaps just open a dispute and return it, one will show up on a consignment site eventually.
