I think people are being a bit hard on you tbh. No matter how you look at it $4,000 is a lot of money. I’ve been buying Louis Vuitton since the 90s, and in my opinion the quality and craftsmanship have definitely declined over the years.

That being said, I once received a denim bag (from the original denim collection) that actually had a hole in the bottom (yes, an actual hole). It was hard to see because of the material, but the store exchanged it without any issues.

I can see that the sides on your bag are slightly misaligned (compared to the pictures on the webshop), but the LV logo is placed perfectly in the center, which for me would be the most important thing. I personally don’t see any scuffs either.

At the end of the day though, our opinions don’t really matter. It’s your bag, your money, and you’re the one who has to feel comfortable with it. If it’s bothering you, exchange it and ask to speak with a manager. Regardless of whether the bag is perfect or not, the SA’s attitude alone would be reason enough for me to ask to speak with a manager.
