This number called and then hung up

Received a call from this number claiming to be Microsoft Tech.  Eastern European or Russian accent.  Caller claimed that they urgently needed me to respond to a message sent to them from my computer.   He  asked is I was in front of my computer.  I hung up.

got a call at 8:02 am on sat morn. No one on the line. I called back and an operator came on and said this number could not receive incoming call.

Received voice mail from (609) 555-0146 leavinf a message about ' "in-traction(?) which has been executed by the US Treasury Department ' -- transcription of voicemail via Comcast. Xfinity transcription records voicemail as well as originating telephone number. Had an income tax scam call a little while back, and IRS confirmed it was a scam; same thing with call back number different from originating call. Both calls had a threat of court/arrest to prompt call back. Recording sounded like an automated call; had an accent, not American.

Call from a heavily accented male obviously in a call center from the noise in the background. Asked for me by my last name. I asked who is calling. Disconnected. Area code is from New Jersey.
