Account Recovery OSRS - Final steps

After more than a week of attempting to appeal my account, I finally received a response from Mod Erawyn (Jagex #5172697). He informed me that he sent a link regarding the subject 'Claim your RuneScape character.' To successfully import your character, please follow the steps below...
