Hi,
I was able to get Minecraft on my account, so I'd like to explain a bit better why, I think, the results on this process are a bit hit and miss.
In order to understand what's going on, you have to put yourself in the shoes of the support teams at Microsoft, Mojang, really any big organization.
When you have a customer base of MILLIONS of customers to support on MILLIONS of products, it can get tricky.
The Mojang support team is probably not that big, so they can't really handle the volume. The Microsoft team is able to handle volume, but they don't have the tools and process to interact with your Mojang account and confirm that you indeed own Minecraft
Java Edition.
The part where ElleBee2's mentions you have to say you want to _upload a picture of your error message_ is very important. Another thing you should do, copy the link to ElleBee2's post and say you want to have the exact same thing you had. If the email on
your mojang account and the email on your microsoft account are the same you might just get it. But remember that you are asking them to add a game to your account for free, with as only evidence a screenshot that could've been altered ( really, I'm surprised
I got it ! ).
Be patient. Do not say things like: "I feel like this", "I am entitled to", etc... When you say things like that you will cause the customer service agent to become "armored up". It's not only WHAT you say, but HOW you say it. This will have a huge impact
on your success. The peoples in Microsoft support teams are great ! They are polite, respectful, kind and try to help. But they are not engineers, they are bottom of the ladder worker who are probably having a hard time understanding your request. So be patient,
be understanding, don't become the bad guy, be the guy they want to help! Be the guy that they wont want to leave hanging, be a bro ! ( or a sis yo ! )
Good luck !
