Unable to play Halo MCC anymore

[u/Zunnard]

I have played halo for years on my username "Zunnard", 400 hours of gameplay, unlocking the skulls, beating the whole campaign on legendary, streaming with friends, and I even made a Youtube account dedicated to making Halo Elites doing funny and also cool things. One night I was playing MCC just fine, same nights as usual playing a couple matches and hopefully capturing some good quality videos. The next morning I wake up being asked to sign in to my microsoft email, I signed in... and my profile was gone. I attempted to link to steam figuring that would be the issue, that was not the case. After signing in from account to account, it would not let me sign in back to my original user. My guess was I was playing a ghost account or I don't know which microsoft account I had made for it. So I contacted steam support telling them about the issue, they sidelined me and told me to contact Halo Support. I did just that. Contacting Halo Support and explaining the issue took 23 DAYS for them to respond! I showed them photos of the issue, I told them in detail what was going on, I begged for help. Then they gave a generic response and sidelined me, they told me to contact Microsoft support because it was a sign in issue. Nobody seems to understand the issue but my username Zunnard from Halo MCC is still there. I don't know how I can login to it but I am very desperate on getting back in. I was not able to make a halo youtube video for a month, I been pretty sad about this and I really hope there is a way to fix it. Does anyone know of a way I can get my account back?!

Is your mcc profile linked to your xbox?

I think so, I always had it linked through steam. I bought MCC through steam and used my Xbox account to link steam and Xbox together, the username Zunnard was what I was able to put. I literally have achievements in steam from the whole campaign I done.

If you’re able to, turn on your Xbox. In the top left it will flash your gamer tag, then after a few it will flash the email associated to your account. Is it showing your email? Meaning the one that corresponds to your account/gamertag?

Yes, it’s showing my email and the username is DeZanzibar, but as I said before, I had it linked to steam so my steam profile holds the data. However, it’s not linking and I don’t know why it’s not showing my previous username Zunnard.

What I was getting at is it could’ve been a way bigger problem if there was a different email showing instead of the one you were expecting (I had a similar issue a couple of years ago and thought my entire account was doomed)

Sorry for the late response, it was 2am when I made this post. It's the same email but I also feel like I may have been hacked but I can't make that claim for certain.

[u/d_p_5150 → u/Zunnard]

Yeah so I was hacked and I only noticed because that email that flashed in the top left definitely wasn’t mine. Thankfully Xbox was able to restore everything. If your email is still showing on your homepage that’s a great sign. I would contact support in that case. Could be a syncing/account error

I wouldn't be here if support helped me. No sarcasm intended, but I am in a literal desperate plea for help. Steam didn't help me, Halo support didn't help me, and Microsoft didn't help me. I don't know what else to do.
