Hacked Microsoft account/Problems with migration from Mojang to Microsoft

Hey, I have an issue.

I tried to log into my Minecraft account through Microsoft, because I've already migrated and I've never had an issue with that until yesterday. When I tried to log in it kept saying that there's no such Microsoft account registered under my email address, which is pretty weird, since I haven't had an issue like that. I think it's good to mention that I have two email addresses that I use, one for my Microsoft and the second one for other stuff - now I've used the second one for Minecraft and I'm pretty sure I've made a new Microsoft account with it just to migrate. Now when I tried to log in with my Microsoft address it works but it's my Xbox account which I never even used and it says that I do not have Java edition, (it just simply says I am warez), hence why I believe I migrated to the same address as I´ve used for Mojang and not this one. This all made me think that it was a migration issue and that I am dumb for not remembering which address I've used until today - today I tried to log in again with my normal address and it asked for a pin, which did not work of course so I tried the "Use a method not listed here". Now when I clicked that it was basically a window where you use your password instead of your pin, that's nothing unusual - what's unusual is that under the "Forgot your password?" line it said "Email code to ti*****@mail.ru". That would not be weird at all if "ti*****@mail.ru" was my email address, which it isn't. That's how I came to the conclusion that someone most likely changed my email address, and it would not be that strange since just few hours prior to that I received an email sent from my own email address to my own email address. The contents of that email were pretty much just my exposed password and trying to blackmail me into sending them bitcoins. Since then I've changed my password, but it did not come to me that someone might try and steal other accounts. Now of course, these two occurrences might have no connections with each other at all, but it would make sense.

Thank you all for your help.
