How do you deal with returns on your business

If indeed it is our fault as sellers then we will accept the return, if it is not our fault but the expedition's fault then the customer must complain to the expedition, don't blame the seller. The point is to remain professional both as a seller and a buyer.

That's why you have to put in efforts to make sure packaging doesn't allow goods to be damaged on transit. If it happens though, you have to take the loss and move on. Make a replacement for your customer.
