AT&T is a far cry from the original company (before the Carterphone Decision and the breakup). The company
was a national treasure in those days. The customer service (free phones, free replacement phones, the best in the world quality, etc).
Bell Labs was the foundation for much of what we have today.
It is sad they have disgraced the name. I get 3 to 4 solicitation calls from them each week. The people are probably contractors (they
can barely speak english). They will say anything to get you to upgrade your phone/internet, etc. What a mess.
