Amazon FireTV Cube registered to another account

I recently ordered two FireTv cubes, and I plugged one in. I added it to my account but I contacted tech support from Amazon about it and was told it was on another account and I needed to swap it out. Is this a problem and if so how do I go about fixing it? I know the box came and was marked “Refurbished” but when I pointed that out the support chat said that since it was on another account it would be deleted from mine. Is this true?
