Who called from 3025264184

N/A

I reported this number and the consumer protection agency would not do anything.
I believe this is a secret  government agency.

Received unsolicited call from this number and my phone number IS registered on the do not call list (615-482-3874) thank you

Respectfully - simply posting here does nothing to stop such calls.  If you are on the national DNC list, you must go to the government page (or call) to report a violation.   If you number is a cell number, download and list the number on a call blocker.

If you have spoken to the caller and they are a telemarketer and/or other scam - document everything you can and then make a report to your local BBB and your state's AG.

A SUPER loud call center asking for a CEO of one of our subsidiaries.

Didn't ID himself or his company, but based on how LOUD the call center was, it was more than likely a telemarketer.
