As a loyal Bergdorf Goodman Landmark store customer I have to come to their defense. When you order from BG ONLINE, your item gets picked by a warehouse clerk who knows nothing about designer bags or designer anything for that matter, they pack it and ship it, when an item gets returned, they put it back into it's slot and process the refund, they do not check to see if it is authentic. They should start putting tags on their bags and I bet they will do so soon.
If you want to make sure you get authentic items call the store. If you want excellent customer service call Jody directly and have her pick your BV bag right personally from the selling floor. Jody is the bv expert at BG. Bergdorf Goodman only has one store, the one on 5th Ave between 57 & 58th streets in NYC.
Sorry this happened to you, but the scammers are to blame and BG needs to start using security tags.
