Caller: Claims to be federal department of home affairs??

Automated voice as soon as I answered claiming a number of court cases are being filed against me and my identity has been stolen!?!? Asked me to press 1 to speak to a federal agent?!? I hung up as I doubt federal agencies would be calling from a mobile number or using an automated voice which must say the same thing to every call it makes unless some genius is customising each call rather than a human being just calling. Be careful, it’s a bit terrifying and I hope no one gets scanned into handing over any personal information
