Re "Secret cellphone tracking" (Page A9, Aug. 25): The phone companies have a lot of data on us. The probably get paid well to provide it to the FBI. Now we read that private companies can get this data and sell it.
Tangentially, why can't the phone companies stop/block the daily spam calls about credit cards, utility costs, etc? I have 10 blocked number slots, but these companies change their telephone numbers every day and often will not answer even if you call back. If they do answer, they hang up as soon as you ask to be put on their do not call list.
The phone company can see all these calls and should be able to quickly determine which are spam calls, just like our ISPs do for spam email. Why is there such resistance to good customer service?
