This app is great until it isn't. I shipped an item to a buyer, the package was delayed or something and the seller was able to cancel the order. Mercari says I can't get a refund because the weight was incorrect? Why would that constitute me not getting a refund? If the shipping weight was more than I anticipated then you should've just taken the difference from the price of my item. instead, you have just stolen my money. I submitted a claim and nobody has replied. Just lovely
