Product not as described

Hello,I ordered a digital code for the game Call of Duty: Modern Warfare 2 Ps5 – Cross-Gen Bundle Instead of a digital code, I received a document with installation instruction to install an unknown account on my PS5 and under this account I should install te game. I don't want to install an extra unknown account on my PS5, I just want a digital code which I can use under my own account. So can you please refund this purchase or send me an unique digital code.Many thanks!Best regards,Glenn Goossens
