Can't unlink my banned psn account from my Microsoft account

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Giantaaron2010 the department responsible for bans and suspensions is Enforcement, if your account is banned and you don't have access to it unfortunately you won't be able to unlink the account.

In these cases, unfortunately, even Xbox support cannot help you.

I just bought Minecraft on my ps4 account and when I went to log in, it said that my Microsoft account is already connected to a PSN account. How do i unlink a Psn account from my Microsoft account

Yes

Hello, a connected account can be unlinked by clicking the unlink button in the settings on the ps5 minecraft app, I do not have an account connected to my psn, I have access to my microsoft account, i never connected any account to my psn and this is the first time im attempting to connnect, My psn is not connected to an account

ok so that day i unlinked my account because i was trying to log in an alt account but i couldnt for some reason , then i created another psn account for my other account and logged in whilst my main account was unlinked . I left home with my alt logged on and my main unlinked . Then i came back home and i couldnt log in my main . 1 week ago i unlinked my alt from my alt psn account trying to log in my main psn account with my alt . But in a matter of seconds of unlinking my account and switching psn , it said it was allready connected even that i unlinked . I can still log on xbox app and minecraft on my phone

I linked my Microsoft account with my father's PSN account when I was younger because I didn't have one of my own and I wanted to play games like Minecraft and such with friends online. Now that I'm a bit older, I was hoping I would be able to link my Microsoft account with my personal PSN account, but I can't get in contact with technical support from either Sony or Microsoft as they just throw poorly programmed bots my way that don't answer my questions. I can't even find the instructions to unlink my Microsoft account from my father's PSN account to begin with.

Can someone help with this? And if it can't be done, can someone at least explain why?

The short answer is no. Its not possible.

The long answer is:

LINKING A MICROSOFT ACCOUNT TO A PLAYSTATION® ACCOUNT

Note: Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.
