BlackShark v2 x, wires ruined :3

Hello, I got my headphones from a store in my region(portugal), but I was wondering if I can send directly to razer so they fix my wires? Anyone know? They told me it would cost me 20eur just to send the headphones, and more for the repair, if they are gonna send the headphones to razer I rather send them my self The wires got cut, cuz cats... wonderfull right, I had my headphones for like 3 months
