Dear xxxxx

Thank you for contacting Fon Customer Support.

I checked this router in our system and it is assigned to another customer account.

Could you send me with a picture of the backside of your router just to show the evidence that you're in physical possession of it.

Look forward to hearing from you.

Kind regards,
Jarek
