Even the FTC couldn't seem to stop these guys for weeks (months?) from not only robocalling but robocalling in an attempt to defraud people. And though their assests have been frozen, their website's still up. Not surprisingly, the company seems to be run by a bunch of former criminals.
We still have our landline. Hitomi insists on keeping service, and though there are just a few good reasons. 1) Reliable emergency service. 2) Cheap(er) international dialing; though I suppose a calling card and cell phone would work to call Japan. 3) Authentication with credit card companies or whomever requires an actual land line. (But I don't even any company requires a landline anymore.)
But we don't answer my landline anymore. The rare occasion I use POTS, I actually find it a bit quaint to listen to a dial tone, and not have to hit any buttons.
