Problem with steam linking

[Mazz0]

I want to post on a rep thread but after logging in it says that i must sign through steam and after doing that a message says that my steam account is linked to a different sop account and i need to unlink.

How can i unlink?

How did i link it to a different sop account since that i have 1 sop account?

Thanks

You already have an account here, Mazzo, alt accounts are not allowed, nor do we unlink accounts, please add me on steam to resolve this issue.
