I made the mistake of claiming my twitch prime loot before I linked my Blizzard account to my Twitch account. How do I get my prime loot now?
I'm a little confused by your question. Did you claim the loot before the correct battletag was linked to your COD account, or your COD account not being linked to your Twitch Prime account at all?
Your battletag/battle.net credentials need to be linked to your COD account first and then your COD account to your Twitch Prime account last. Make sure those are all linked correctly before trying to claim the rewards.
that doesn't answer the *****ing question. Did you even read what he wrote?
