You stated "this is completely unfair considering the age of the computer its a brand new device" - Microsoft offers a 60 day return - see https://www.microsoft.com/en-us/store/b/returns If you are outside the US, there may not be a return button on your order and you'd need to contact Sales Support https://support.microsoft.com/en-us/support/ (scroll down)
If you bought from a different retailer, you would need to check their return policy. But if this is a brand new device as you state, your best option is to return for full refund and repurchase.
No one if these forums can look up case numbers.
