Who said he isn't reasonable? The issue here is sloppiness that caused this whole unpleasant mess. Why on earth would you write Last 202 on your webpage when you have a shoebox in front of you that says Last 82? Wait, let me guess, it's because "mistakes do happen", right? But when you are selling shoes for over 1000USD to foreign countries you should know that what might be a minor problem to a resident of New York can be magnified many times over when the recipient is in Asia.
Maybe Leffot should stick to walk-in customers if they don't know that selling on the internet means putting out accurate information on their products.
My definition of good customer service is not letting bad things happen to begin with. Not taking my money on the pretext of wrongly marked products and then trying to be helpful.
