Q: apple id locked

hi

i have iPhone 6 with iCloud id on it and i want to remove it.

my brother tried to enter the password several times and locked it.

i know the apple id and the pass but..

the apple id is ****@icloud.com so when i enter it ,it says that it is disable and i need to unlock it

i don't know the security answer but i choose send by mail .

but how can i enter the mail?? cause it is @icloud.com mail?

i replace the pass 10 min ago but my brother type it wrong so now it is disable.

what can i do next

how can i enter the apple id and pass (i know them) ?
