You probably got hacked and freebitco.in has nothing to do about it, also hacks are notoriously happening in this website. I have a personal experience about this on my own and they have send me multiple emails regarding about someone trying to log-in to my account, they even provided the I.P. address (Ukraine) of who is trying to log-in to my account and after several failed attempts they temporarily locked my account and gave me a new password. You may not have the same experience as me because the hacker knows your password on your account or email that's why they got into quickly. Maybe you got victimized by phishing site or malware that's why they were able to get your password.
i not get hacked and also not get any email about failed logins

If this is the reason I bet freebitco.in will email the email address of OP to inform that there's someone who changed his passwords but base on hi experience there's nothing he received.
And to let op know that freebitco.in forgot password always show that message whatever you input on the email textbox
So try to double check your email if its correct and if its registered on the website.
my email is correct and i get this email after 3,4 hours on the day i couldn't access my account
and my account was verified when i got this email
