So, when you get your console call xbox and tell them you never ordered a console and dont know why you got it. The explain you were in fear of getting billed etc. They will ask you to ship it back and raise it to tier 3 to find who really made the order (and it was you). Dont ship back the console and then you cant be billed 
They told me I wouldnt get billed because I didnt order it.
