ALERT!!
My daughter, 18 yr old college freshman, signed up for Cell One (now ATT Wireless) with me as a witness. The sales person was the manager of a local office. He called credit and stated that, since she was so young and had no credit history, ATT would only give her a $100 limit/mo. At an expenditure of $100, her cell phone would shut down until the bill was paid. LIES!!! Her first bill was $300! They had a million excuses why that was, clueless staff manning the phones, and a supervisor who would not call back. First offer: cut the bill $100. My daughter was too young for the task - they ran roughshod over her. Finally, armed with names and dates, I wrote the prez in San Fran and his assistant called to tell me that they would accept her $100 payment as payment-in-full. Cancelled the phone, needless to say. A competitor told my daughter that there was a class action lawsuit over this very issue. Could not find it.
Let this serve as a warning.
