Caller: Tax scammer

I've been getting calls from this number and a private number and not answering them but they left automated voice msgs in my msg bank saying that my tax file number has been suspended due to a Federal Court matter and if I don't press one to speak with someone I could be arrested! I googled tax fraud phone call scam and on the taxation dept's website there is a warning about these calls not to press one ir talk to anyone from these calls!
