Didn't receive my rank badge

One thought I had is that because so many cases were created, even if unintentionally, the system may be automatically closing the newer ones.

Could you please go to your My Cases page, find the earliest case you created, resume that one, and then wait there once more?

I do understand why you are anxious to get this sorted. But as you mentioned, you reached Predator on Switch, so this may still point to an account syncing issue. Once you are able to connect with support, that is something they should be able to help resolve.
