Whenever I try to Register my KRAKEN V3 X, it keeps giving me an error message.

Whenever I try to Register my RAZER KRAKEN V3 X, it keeps giving me the error message "There was an unexpected error. Please reload the page and try again." I typed the serial number in correctly and all the information is correct. This is not a user error. There is something wrong with RAZER’s registration system. When I asked them if they could register the product for me, they refused and said that if I get this error message then I can never register this product. Why can’t RAZER manually add the product to my account instead of telling me that I can never register a product that I bought from them?
