As said in the title I’ve registered the product but i did not receive my activation code email.
I’ve looked around support page for getting one but when I use that link it goes back to the product registration page and then asks me to register my already registered product

Redirects to a login page after doing so leads me to this page-

here i select my headphones that are registered already but i did not get an activation code for.
I select my headphones then I am sent to this page which asks me to register my already registered headphones

I’m not sure how they expect me to register an already registered device
PS: If i go further and try to register it again, it shows device already registered to user
