I will have to do some investigating to discover more about this "authentication" agency, but for now I can say with 100% certainty, they are totally wrong.
The bag is fake, absolutely and definitely.
Perzacly what I told the seller. I just can't access the actual website, which is too weird for me.
Ebay has been advised.
Keep calm and enjoy a cold chardy (aussie slang for chardonnay).
Oh my!!! Now they are faking the authentication process too!
