I hope they help you with this. I looked at the photos again the the peeling is in an odd area. Meaning if it was scraped it seems that area would be hard to do..isn't usually the bottom corners are the ones that scrape?
I agree with deb68nc, this isn't an area where I'd normally expect to see scrapes from normal usage, and if there was a scrape here I'd think the surrounding canvas would look scraped too but it doesn't.
OP, I hope LV can resolve this to your satisfaction. I have two DE bags and each one has a small amount of rubbing on the corner piping (likely from the bag bumping into something or scaping something), but NOTHING like this!
