Steam connected to two accs, but both says I can't connect CSGO



Yesterday I made my first FaceIT acc, atleast that was what I thought at the time. When I tried to connect my steam acc it worked but when I tried to connect CSGO I got the warning that my steam acc was used somewhere else, so I remembered I made one last fall but hade trouble connecting CSGO so I never used it, tried to talk to support but didn’t get any respond so nothing happened. So now I have two FaceIT accs both are connected to my only steamacc and neither can connect CSGO because they both say that the steamacc is already used somewhere else.

What should I do? Is there some way via Steam to see how my acc is connected and to what users etc. I am sure I’ve only made two accs and I’m the only one with access to the steamacc.
