I received a call from a random Australian number and declined it, they left a message. This message was an automated voice saying they had my name down at the home of federal affairs and was launching an investigation into me, as my name had been down under illegal activity and had a warrant for my arrest. Then the person said to press one to speak to someone but it was a voicemail message so I hung up and deleted, very worried who could possibly be using my name or trying to scam me to clicking 1 on the phone. The Saturday before on the 11th of July I got another call from someone in Australia that I also didn't know and left a message of no noise. Keep in mind I am 16 and go to school and play sport and volunteer, I have not done anything that would be suspicious. Do I have a need to worry? I feel like if they did have a warrant for my arrest they wouldn't call and say that, no?
