These people won't leave a message, have called every 30 minutes today, three times in a row. A search of this number comes up with "Daytona Beach, Florida, Nextel Communications, Inc. on a Cell Phone." If a real person doesn't start talking, I don't pick up the phone.
This is a group of numbers which are not valid. I called a couple of them and operator said number not in use. I currently have 904-677-3573 through 3577 blocked.
They're at it again, group of numbers for 904-677 so all you can do is block them all......3574, 3575, 3576 3577, and probably lots more. They won't talk to the machine, & I won't pick up the phone.
