SolvedMinecraft account hacked.

Hi, my sister has one account (AnaGamerHD) but she was very short of mind and shared the password with one guy who says "im gonna give you one free cape" and his account was hacked (password changed)... but the problem was the next:

The gmail what she used for register the account whas from my father and he closes his gmail account and now we can't talk to the mojang support because we don't have how to prove that the account was of hers...

So the question is: ¿How can i recover the password? (i tried cracking but don't work (with 20k user passwords)... )

Thanks.

If anyone can give me the password, im gonna give to you a small gift

i dont find this possible, You need to verify your Password When you log in from another ip

if you bought minecraft show proof of the transaction id.
