I received a call from this number this morning and didn't answer. A man left a message saying his name was James Caston(?) and threatening government is going to get you.
There was a message left on my voicemail stating that if ignored it would be a violation of some law. Once I called back they said that there was a warrant for my arrest for tax evasion and when the call was over authorities would be at my house within 45 minutes. They told me I had an outstanding tax debt of almost $7,000. Reported to local authorities who said it was a scam.
