Go on their live chat and tell them. Don't ask for a return or a refund, just say it arrived damaged. They'll usually immediately place a free replacement order for you. If they ask you to end the original back, which 99% of the time they don't, make a fuss over having to pay for the international return shipping if they can't give you a free return qr code, and normally they let you keep it. Hopefully you'll have better luck the 2nd time
