how do i relink my steam account

I accidentally unlinked my steam account thinking it was an old one since its been years since i played an ea game, it wasant and now im locked out of my newly bought game and i cannot find a wy to contact support. there is no "chat with an advisor button" as the stupid bot suggests, there is no "contact support" button there is no help regarding this and it keeps pointing me to the forums where someone points the the help page which is useless. ive spent hours on this and i just want to play tf2. utterly garbage system and website.
