HI there- I hope this can be of some help, it took a lot of calling, sweating, and frustration and pulling out hair out of my head (literally). Rememer a few years ago when LV had the Murakami cherry blossom stuff? I had bought something and had understood from the salesperson who ddidnt speak English (we were in Maui), that I would receive a credit to my CREDIT CARD if I returned it in 14 days, so I stupidly thought pick up the few bags I couldnt decide between and then what I decide against, return it.
Apparently it was MY fault for not understanding the LV sa who didnt speak english, that what she meant by credit card credit was "store credit". Nice, I had $3K in store credit when I had a fat Amex bill to pay by the end of the month. Fine. Yes I did argue etc, but apparently it was all my fault.
So to get myself out of my rut, a friend of mine helped me photo it and I ebayed the bags with photos of the receipt etc.
Ebay ended the auctions with the normal BS they give. So after a LONG time emailing ebay and those emails going into limbo, I finally got a hold of someone at ebay (back then even phoning them was hard too), who explained a few things to me.
So you can have an authentic item, but if you post ads or anything that is of "intellectual copyright" (ads, catalogue pics, pics from their website, stuff that they actually own), your item can be reported and pulled. Even certain wording can have an item pulled she had said. Remember a long time ago people would say "if you dont like it, take it back to the store and get a store credit", that got listing pulled immediately, as does " get it authenticated at the boutique". She said to stick to the facts (to me) and to not involve the boutique "get it authenticated" etc. Oh and no ads.
So I too had thought it was because they thought my item was fake, and instead it was because I had a magazine ad and a sentence seemed odd to them (I guess it depends on your grammar maybe). So this eas the ebay lady's advice to me. I only auctioned stuff that one time and when I relisted didnt have a problem.
I hope this info helps someone out there.
