The Caller ID only shows this caller as TOLL-FREE-CALLER only. This caller keep on calling at all hours of the day or evening repeatedly. Moreover, this caller even calls more than once in a day. This caller's phone number is very similar to (866) 948-8559, which makes me wonder if the two are related, or from the same caller. These two numbers never ever leave any message upon my answering machine. And if I try calling back either one of these callers, they never ever answer my call, and let the phone rings off the hook instead. I am only able to block so many of these type of callers at one time. I wish there was some way I could block this type of caller. My phone system only lets me block a limited numbers of callers. Furthermore, my Home Phone landline provider, only lets me block local numbers. There's a lot of misunderstanding with the "do not call" list. It only keeps legitimate marketers from contacting you, not the unscrupulous ones. That's why most of them hang up. They're hoping for a live voice, preferably a senior, who they can catch off-guard and spew their nonsense, and maybe even get a credit card payment. I have caller ID and I just don't pick up calls from numbers I don't recognize. And never, ever has one left me a voice-mail! Better federal legislation is desperately needed, but good luck with that. The most you'll ever get is a crappy Sunday news conference by a phony like NY's Sen. Schumer or worst, but nothing will ever happen.
