Twitch drop not received. Blizzard 30 anniversary

It’s been about three weeks since I claimed the 30 anniversary drops on twitch and I have not received the rewards.

I open a ticket and after providing evidence they have not been able to fix it. The GM asked me to submit a bug here.

I submitted evidence on my ticket that my BNet account is connected with my Twitch account and that I claimed the reward three weeks ago

I originally posted the bug here

Please help, I don’t want to miss the opportunity of getting these rewards because of this issue.
