“Hey there, I must have missed you. It’s Jessica over at National Debt Advisory Services, LLC. I tried to last week as well this is a follow-up notification regarding the new zero debt program that is now open for you it looks like you possibly have some past money that you owe which we can squash with this new program we can eliminate all your unsecured debt such as medical bills credit card debt and Loans basically they become non collectible but you must elect to enroll this month so give me a shout back at 88”

They are now going as “National Debt Advisory Services, LLC.”

Thanks for the mention of the new name. NTAS has been the defendant in some other TCPA cases. If you look up Rebecca Miller v. [NTAS], there are actually two cases. As I understand it, the plaintiff won a judgement aginst NTAS for their robocalls, and NTAS continued to call her.
I think Shane Scofield and Mabel Arredondo might also have settled with NTAS, but I don’t know if either plaintiff has been paid yet.
I got four “ringless voicemails” from them in late Jan./early Feb. using the name “U.S. Tax Experts.” Calls to the numbers given in the voicemail are answered as “Tax Group” (a name that appeared in one of the other TCPA lawsuits I’m aware of), and eventually get transferred to NTAS. Some people answering the phones there seem to think they’re doing God’s work or something. The FCC ruled not long ago that ringless voicemails are a TCPA violation.
The originating numbers, all from my own area code, are a mix of CenturyLink and other carriers. They aren’t exactly spoofed. Calls to those numbers usually go to a recording that says something about “No one is available to take your call. Press 2 to opt-out.” Well, I never opted-in, so I might hafta sue them, too.
The callback numbers left in the voicemails also seem to be all or at least mostly Telnyx numbers, too. In two of the voicemails, the robobimbos gave two different callback numbers. I hope there’s a way to subpoena subscriber info for a civil case.
As always, good research, OGE. What are you using for reverse lookups these days?

A combination of and You can just call me by my last name, Goodenough.

Got it. :+1:
I;'ve been using NumLookup for awhile, probably after a mention I saw on this site, but this is the first I’ve heard of zlookup.
Thanks again.

Numlookup limits free users to only 5 lookups per day, so I double that by also using Zlookup.


Zlookup looks like Numlookup used to, with the Captcha and all.
I think a subscription is needed to get user info, and I did subscribe to NumL. I have to sign in to get user info.
