This translates as:
I bought my Black Shark v2 x and they had already redeemed my code.

Hello soloDeepCoffeeinsight772,

If you just recently purchased the headset, I suggest you take advantage of your warranty from the seller, as we cannot remove the device from the previous account. To ensure the authenticity of your purchase, please buy Razer products from  authorized Razer resellers. This guarantees that you receive a genuine device. Please be aware that products purchased from non-authorized dealers may be used, counterfeit, re-boxed, defective, or gray market goods. If you need assistance in the future, feel free to message me and let’s continiue our converation in English. All the best!
