Should I call back 0401 278 398 if I missed their call?
Not immediately. If the caller had a legitimate reason to reach you, they will typically leave a voicemail message.

Wait to see if a message is left, then research the number online before calling back.

What should I do if 0401 278 398 keeps calling me?
