Louis Vuitton Debacle

I thought there was no one better than Splendora readers to understand my frustration. 5 years ago I bought a Louis Vuitton bag from a luxury store; fast forward to 2006-2007 I have grown out of my desire to carry bags with labels on it so I decided to take my bag to a consignment shop that I frequent. This shop sometimes deals in high end items so I felt comfortable taking it there. To my surprise they examined that bag with a fine tooth comb thought it was a fake, but took it anyway because I am a frequent client and had some level of trust. Well two weeks later they gave me my bag back and said that under further investigation they have decided the bag is a fake. I thought it  was no way to get my 275 dollars back or even authenticate this purchase, luckily the store still had my purchase history on file and I was able to retrieve my order unfortunately the email I sent to the company bounced back  and they still haven't returned my message I sent over an hour ago. I’m just wondering if they are going to give me my money back or authenticate this item?
