Hi,
At the moment I am still have a ticket open in discord with the community manager and he is trying to get more information about what happened.
I want to wait a bit more (few days) to see the outcome of that, before I take next step to casino guru.
Another update is that I noticed yesterday that the reward was indeed credited to my account, but removed by an admin:

Thanks so far for all suggestions and remarks.
