well amazon is really easy.
You buy some stuff, tell them that it didn't arrive/box was empty ( or use a private method that's way better ) and they just refund your purchase.
But steelseries used to be so easy, but they patched now even people who legit send their stuff back don't get a replacements
They do I believe, but its a different system now. Now they have to confirm arrival of your broken product first, before they send you a new one.
