Lost my main account after Riot account updates

Hello everyone,

I have had two accounts. When Riot updated to Riot accounts when I logged in to my main I was asked to create a new account or something along those lines. I did what I was asked and I ended up with level 1 account. All my skins etc are gone. When I look up my name on op.gg or similar sites its like it does not exist anymore?

Can anyone help me

The problem is that it is a very old account so I do no have access to account setup details....

Regards
