Not exactly valid info... I would agree that it COULD possibly be sold as a working number but hackers? Anyone that buys in to the "TAX" collector or product, deserves to lose money and those are the people I laugh at. Nobody is collecting voice samples.
I have had constant calls from this same business Multiple times, some from Ohio, some from California, tried to talk to someone and was instantly hung up on. They continue to call I am gonna file for harassment and take not only their business to court, but also Google for not taking action sooner vs these people.
Either sort it out or deal with the repercussions.
