It looked like your Authentication request didn't get an answer and you probably bought your Cabas Piano and it ended up to be a fake. Don't try to be someone that you're not.
If you can't afford a new one, buying a used one is OK as well. Just don't buy a fake one. You can fool yourself, but not other people who knows LV.
FYI. LV can only be purchased at the LV store. LV does not wholesale or give discounts. The HK site you bought your LV at only sell fake stuff.
