Oh, so the seller didn't respond to you? And, the sales tag may have just been the tag you received. I have a Valentino, and I also have a blank red tag. There is nothing inside of the red tag. Some outlets may not include other tags to prevent store returns. But, I suppose if you aren't satisfied with the item, you should return it. It looks perfect to me. I've also looked on eBay for completed listings, and saw another bag like yours, and it has folds on the bag also, and it doesn't look too different from yours. I've noticed that the photos you took is a photo of the bag farther away, than the other (by the lighting of flash), the close-up of the leather is supposed to be that way. It's not perfect, and smooth on the whole bag because of that type of leather. I also know that with use of the bag will probably change the way the leather looks as opposed to when it's brand new. If all you want back is the undisclosed tax amount, there shouldn't be any problem with you getting that back since you've stated that you filed a dispute for that.
Good luck
