The person said that calling from US government.
Strong asian accent and couldn't get the exact department name.
And she hang up when I told her that US government won't contact to any individual by phone.

Got a call from this number that said in a computer generated voice "Please Die", WTF. Thats messed up.

Bad static & tons of telemarketer sounds in the background.  They said they were from the US Government and rambled on something I couldn't understand.  When I again said please repeat because we are having a language barrier, I still couldn't understand, I asked her who she was trying to reach specifically and what was this call in regard to, she sat there in silence.  I hung up after that.  Stinks of a scam.

Called a couple times.  Did not leave voice mail.

I don't return calls from people who don't leave a voicemail, because most of the time they are robocalls,  telemarketers or scammers.

Young Asian lady called and said she was calling from the US grant Dept. I qualified for a $200 grant that didn't have to be repaid. The money would be direct deposited to my account. I asked how they had acquired my number because it was a business work number... and she hung up.
