It is SPAM

It is not safe, it is a scam.
my message says an order from Optus has been delivered, but it is not true

Caller: They txted

Contacted Optus to clarify this. They never sent me anything. (I was having trouble with nbn so wasn’t 100% sure to begin with) I did not click the link because it looked like a scam and it is!! Beware

Kept sending me messages about my order has arrived which I don't. Very dangerous number.

Caller: 0436 192 843 spam

Pretended to be startrack with a delivery for a brand I didn’t purchase. Do not click on the link!

Caller: scam

No parcel ordered, kept sending msgs advice deliveries. Stop! Scammer.

Scam

Message received was "Your parcel NETZ... has been delivered". Quite obviously a scam as I had nothing ordered. The scamsters are very organised, the positive messages on here are from the scammers.
Do not click on the link in the message. Australia Post does not send links in their text messages.

Advised there was a delivery, no one home so parcel has been left as advised. Do not reply. No parcel has been ordered or expected! No follow up possible!

Caller: via text/sms

Texts/Sms's from this number are spam and should be deleted immediately! Do not click on any link on the text, as it then enables the scammers to ghost your phone and clone phone data..
