Unable to re link origin

I unlinked my origin from tracker network and now I cant relink it. Its the same account that was previously linked (just changed name through Origin) and when I tried to relink it, I get an error that says “Unable to link the Origin name to your account. Shadow_FighterNL is already linked to it.” I’ve never heard of this Shadow_FighterNL. I literally unlinked and tried to relink within the same day and it says that. Any Ideas what I can do?

Why can i not get any help with this. Why should we need to pay to get support help. If this wasnt the only site or tracking i wouldn’t use it. I NEED to link my ORIGIN account, It will not let me
