N1,
Cool shoes I guess? I actually have the AE Chelsea boots, but my chukkas are from Crockett. Probably got the boots on a seasonal sale and the chukkas at list cause glhf. One day I hope to move out of this middling price range, but that would require me to actually realize some professional goals.
Here is what I would do in your situation (albeit speculative since I don't buy from weird online places):
1) Contact retailer - You did this! Great!
2) Contact my CC company and chargeback due to them delivering the incorrect goods and being unwilling to accept a return or exchange.
3) Reach out to Common Project and see if they'll do an exchange. Write a nice e-mail or a real letter on a piece of paper explaining the situation (love their product, saw a sale, didn't vet the retailer, got scammed, etc). Many companies are willing to help out their customers in weird situations since like... America customer service. (GLHF doing this elsewhere, maybe Canada?)
Let me know how that goes. I know $350 is like a weekly take home for you, so you may want reconsider your purchases. Seems like a lot spend on shoes relative to your income.
What do you think about these:
