I also got an automated call from this number. I googled the number and was directed to this website. This website reaffirmed my initial thoughts that this was a scam. Then my heart sank since others may fall victim to whatever these people are up to. I never called them back. I'd assume the government would write me an official letter if there was any issue. (had to listen to the VM a few times and I still didn't catch exactly what they said in the beginning)
They called me an hour ago. Lady was Rebecca brown and the guy is John Parker. I knew it was a scam so I've been calling them back over and over giving false information and asking why I owe money and am being arrested. This scam makes no sense since they never tried to actually get any personal info from me other than name and phone number. After the 3rd time calling back the lady answered and said Mr Smith why do you keep calling here you are going to jail and hung up. Just call and mess with them if you have a few minutes trust me it made my day better by making the scammes waste time and sound like idiots.
