Who called from 3079200621

They pretend to call from Washington pretending to be from the US Government

I answered and heard a ladies voice as a Spanish speaking prompt. Careful with these unknown callers. Spammers/hackers can gather a few bits of information from you by simply confirming your line is active and your voice. That's why sometimes you may recieve calls where you answer and the caller doesn't say anything until you hang up. That specific technique can be used to track your location.

Got the call. No voice message. When I called back it's not in service.

No message.  Disconnect number if you call back.

307 920 0621 called twice in a row just now, did not answer, no Voicemail was left. Yesterday a similar thing happened with a different number. Looked that number up as well found multiple complaints. Apparently it was a Bank of America fax #
