The Caller ID only shows this caller as being TOLL-FREE-CALLER. However upon doing some research, my findings shows this caller as Life-Lock|Telemarketer. This caller calls at all hours of the night and day repeatedly. They never ever leave any message upon my answering machine. And if I try calling them back to request being put on their DO NOT CALL List, I either get a recorded message stating "This number is no longer in service. Thank you. Have a nice day.", or they never ever answer the call, so the phone just ring itself off the hook. I wish there was some way of blocking their calls forever and a day. But with them hiding behind and using a toll-free number, they are able to spoofed around my best effects to block their calls.
