@ OP
I had this happen to a customer once. These ones were smart though. He would change his password and then it will change again. Ended up that the person who phished it had set their email up to mail forwarding. He would get the password reset button but so would they. Make sure you double check for that before changing password. Other than that you should be good.
Maybe you're schizophrenic?
