We have discovered that the 213 number calls daily to see if a live person picks up and then within 10-20 minutes, we get a call from 800-405-6164 saying that we're a featured small business and they'd like to give us $300 in rebates. They will then say they need to verify your info and want you to give it to them. If you ask them to repeat it to you, they'll hang up. The deal is that once you say "ok" to giving them your info, they use that as a verbal approval to sign up for bogus services which they then start billing you for. After 30 days they then start saying they're going to send it to collections because they have your approval "recorded". It's a total mess and massive attack on our small businesses.
If you try and call the 800 number back it gives you a bogus autmoated message and hangs up on you.
We've already had our attorney deal with an almost duplicate separate scenario and this one is no different. We haven't found a way to stop it and currently don't answer it. When we're bored we'll pick it up and really harass them which I think is somewhat deserved.
