Watch out for scam calls with the number (03) 8658 8733, Will most likely try to sell you something while claiming its a government service, or you will get the typical "Hello this is *Insert name here* from Microsoft, there's a virus in your computer". And for some reason they always have an Indian accent XD

Annoying telco sales.

telecom marketing keep calling everyday even you reject them.

Unsolicited call, try to switch your telephone provider to them.
