Well the main problem is not 2FA security option in fortunejack.
I think there may be a keylogger in your computer or mobile.So i would suggest to give a factory reset to both(computer & mobile) and start a new beginning.
Well may i know your previous id from which you made the account
i can't format my computer (it's my work computer with many CGI software) i will just disconect it from internet and i will format my phone
way do you need my ID?
Just need to try a bit of things.Maybe it helps.
