@MojangSupport so I bought last month a creeper crunch cereal box only to find out the website no longer has a place to put in the codes,and now I'm finding out you stopped production in august but the box was far from expiring. Is there any way I could still get my ingame reward

Thanks for writing in about the Kellog's Creeper Crunch promotion. This promotion ran from August 1, 2020 until June 30, 2022. Unfortunately, the code can no longer be redeemed, and Minecraft Support cannot add the item to your account. ^TK

I'm just baffled they'd still have em there, it was so long ago. I feel a little cheated, as how would I have known
