YOU ASKED FOR IT: KT&T Communications, not be confused with AT&T Communications, has registered several new operating units in Texas. Those companies, "I Don't Know", "I Don't Care", "It Doesn't Matter", and "Whoever", charge about double the cost of some other long distance companies for operator-assisted long distance calls, the Associated Press says. The choice comes when the operator asks which long distance company you want to complete your call. "It's not deceptive at all," insists Dennis Dees, president of KT&T. Dees won't say how many calls his new companies has completed, but said "I Don't Care" and "It Doesn't Matter" were the most successful.
