The more bad thing is, where they take the one with + at sign up, but their login page throws error on email with + sign. Indian Pension Fund, a government website does it. You can signup with example+enps@anything.com but can't login. If you try to login with example@any, it will say email not found. They only way around is either go in person & submit a paper form; or signup from scratch with a new email.
