From the New York Times:
Logging on to Gmail or other e-mail service has become a routine of daily life, completed without a thought. What would you do, however, if you woke up tomorrow, plugged in your user name and password as you always do, but then received an unfamiliar message: “User name and password do not match”?
If you’re a Gmail user, what you’ll want to do after a few more unsuccessful, increasingly frantic attempts is to speak with a Google customer support representative, post haste. But that’s not an option. Google doesn’t offer a toll-free number and a live person to resolve the ordinary user’s problems.
Discussion forums abound with tales of woe from Gmail customers who have found themselves locked out of their account for days or even weeks.
