I mean I am probably being overly paranoid, but they didn't issue a new receipt because they didn't want to mess up anything with the VAT refund process. It was bought under my husband's name and not mine, and he didn't come back with me the next day so they couldn't issue a new receipt and VAT forms. So the true color doesn't match the receipt.
You have IMO no reason to be paranoid. The purchase came from the FSH store with an explanation that
pertained to the VAT as well as your store receipt. Perhaps you can ask them to make a "notation"
under your husband's name with the explanation you were given. If you have a SA that you work with here in the US
explain the circumstances.
H like any other store can make "mistakes"...Your bag is authentic...
