OP, I'm not saying you're guilty of this because of obviously I haven't seen the bag itself - however I can't see any pictures of the interior, only the very top of the inside. If there is damage/stains on the interior that can't be seen in the photos on the listing then the buyer would be eligible to file a SNAD. A few months ago I bought a bag which arrived with a sticky mess in one of the pockets. The seller didn't mention it in the listing or provide photographs, yet when I complained she said that there were photos of the interior on the listing. Unfortunately she elected to use pics with the pocket closed. That was just sneaky and dishonest. I chose not to return it because I felt I had still paid a good price and it was hard to find, so I just cleaned it myself. None of this is an excuse for claiming the bag is fake, though. That's just stupid. I hope you get this cleared up.
