My wife bought me a new razer kraken 7.1 ( RZ04-02830100-R3M1) from hepsiburada.com on Turkey online shopsite. when I unbox there is a card with scratch‑off ticket . I scracth it off to learn my serial ,but sadly it was damaged. I can't see last 4 numbers of my serial. How can i learn last 4 without buying a new product ?. it was a christmas gift and we can't afford another one i can't find a solution on support FAQ on razer website.
