Caller: department of homeland affairs

they told me I had a legal case under my name, and someone is using my identity

Caller: Clever Contacts

If you're getting calls from this number then your personal details have already been leaked and stolen. Number is a front for the company Clever Contacts which have an official business number as seen on google maps. They will ring repeatedly and if you answer this seemingly innocent number they will ask if you're name is whatever your name is, it will be correct. They will then immediately hang up on you answer them and can even hang up on you should you even just answer the call. Not to be trusted whatsoever and the company Clever Contacts should be investigated and face a board of inquiry, something stinks with this call. They use other mobile numbers too. Simply being lured by sponsored Facebook ads from companies that look legit is one definite way to have this shady company be in contact with you from what I know of. Don't answer their calls or confirm anything with them.

Caller: I don't know

Called me so many times, one time I answered and a woman who didn't identify herself or who she is with asked me if I was (insert name) and then I foolishly and unwisely said yes, they immediately hanged up. Scary. If you get a call like this, tell them No if they ask your name and they have the wrong number. Throw them off.

Appreciate previous person reporting. Hopefully Telstra and Optus can get rid of these germs
