They have rang me twice in the last 2 hours,who are they????

These people phone me every night - who are they?

numerous calls this week and everytime i answer they hang up

Caller hangs up when I answer

when i answer the call registers as "missed"

Don't know who this is.

Caller does not answer. I suspect it is a check to see who is home at a given time for telemarketing puropose.

Do Not Call Register https://www.donotcall.gov.au/
Phone 1300 792 958

How does the register work?
Under the Do Not Call Register Act 2006, telemarketers can check their calling lists against the Do Not Call Register. If a telemarketer calls a number on the Do Not Call Register, they may be in breach of the Act, and may face penalties.

Abused me for not showing up for work (in QLD) I live in NSW. Don't know who they think I am?? They called numerous times and in the middle of the night.
