Based on the report, 0421491545 is flagged as spam - an unsolicited call from someone who had obtained the recipient's personal information.

Should I answer if 0421 491 545 calls again?
It's safest not to answer unknown numbers, especially if 0421 491 545 has already called you once unsolicited. Let it go to voicemail instead.
