Has anyone attempted an exchange with Diabro? I ordered a truffle first. It's a great bag, but really too small for me. I'm hoping to exchange for a city (different color as they don't have a city in truffle) and it's really quite a pain. Not sure I should even continue to exchange. They just emailed me that I need to send them the first bag and they haven't agreed to an exchange yet (understandable as someone may try to send them a fake???) so they have to "approve" from there after they get the truffle bag back but they want my money now for the city. Hmmmmm. I was hoping for a yes or no after they received their bag back and then a charge on my credit card. Anyone go through this process with Diabro??? Thanks.
