Bill from AT&T for $13.50 for Directory Assistance calls (includes Fed charges, state taxes).

Never made the calls dialing 10-15-15-8000 number.

AT&T says they can't help what third party companies do, and they can't stop the customer from using other directory assistance services.

AT&T says they are "not affiliated" with "CALLING 10", ILD Teleservices, Inc., but they can do their "BILLING" for them?

AT&T is the one doing the SLAMMING here!
