Is there a way to re link my PSN to my Microsoft account?

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

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.

psn accounts cannot be unlinked, well they can but only re linked to the same microsoft account.

Yah, I'm having this same issue. I don't think I have ever linked my PSN account to a Microsoft account. Yet, Microsoft states I do. I have scoured everywhere I might be told of which Microsoft account I have linked to my PSN account but, to no avail (Microsoft account access on a PC, my PSN account on my PlayStation device, my PSN account on a PC, Mojang's website.) I even tried that backward fix of changing both passwords. Nothing. I agree that the bare minimum should be to tell us what Microsoft account is currently connected to my PSN account but, we don't get that.
