Do you have any offices/institutions for consumer rights advisory in your country like we have here? If so, go there, describe your case and ask whether that shop is legally obligated to compensate you for your damage. If so, set up a sober, determined letter and give the legal details in precise, uncompromised wording and with exact references. A mix of precise info showing you are informed, sober matter-of fact attitude and a believable display of determination to even escalate the situation if necessary (do not exaggerate it, that makes them only laughing), might do the trick.

Or not.

They sold you something that did damage to you, and mishandling obviously it was not?! That means the item they sold is not in order. If they accept to change the console, they admit the fact that it did damage. And then logic would dictate they also compensate for the damage.
