Same reply phone number, but my message was for illegal tax evasion...

Yeah, SCAM...

Message on answering machine. Strongly suspect this is a tax scam. Sounds like a recorded message implying all sorts of dire consequences about tax evasion and wilful misconduct. Happily going to ignore it.

Messages left re urgent financial matter from private number and overseas number. This number given to call where you get a message to leave a message. Obviously a scam.
