"They" have called every day now for about a week, sometimes twice - in the morning, then again in the afternoon. Never a message on the machine. Caller ID indicates the number, as from "Utilities." Other numbers from the same sequence include: 904-861-1550; 904-861-1582; 904-861-1587; 904-861-1589; and 904-861-1990
Several calls from 904-861-1589 with caller ID SIGNAL but with no message. Very annoying. ATT Call Block feature cannot block this number. Another very annoying. What's the purpose of Call Block when it doesn't work.
