Honestly, I would return it to Amazon. Amazon has created an enormous mess by letting people return networking equipment and then reselling it and making no attempt to "clear" the previous purchase with Netgear. (Actually, that may be nearly imposslble.)
There are forum moderators who can sometimes intercede with Netgear to resolve problems like this. You could send a private message to one of them, such as @Blanca_O (click on this link, which will bring up a way to send a private message.) The specific Orbi serial number is key to resolving the problem.
