Hi, My name is Lucas and I bought a Blackshark headset and when I tried to register it on the Razer website, it said that the product had already been registered. I will attach a proof of purchase made through Mercado Livre and the serial number of the headset.
S / N = HN2121D13400045
The hidden information refers to part of the card data used and shipping address
I hope I can solve the problem :)
