I deleted my Google+ account so I can't anymore login to my SO account as usual. When I'm trying to use my Gmail address to recover my old SO account, it gives me a new one. I tried to log in with Facebook and SE account, but both are giving me a new account.
I've got only my e-mail address that Google+ was based on, and found my old StackOverflow profile page. That's all I have. What can I do to get my old account back?
