Hey, AT&T customers: be very, very careful when dialing three-digit numbers. If you’re trying to dial, say, 211 or 311 (local government information), 611 (AT&T Wireless customer service) or 711 (TTY relay), and you dial 411 for directory assistance by mistake, you’ll be charged for it even if you realize the mistake and hang up immediately. And you’ll need to live with the consequences of your error, since, according to reader Stephen, AT&T will not refund these charges.
