Texted me claiming to be from a company called NCML asking me to call another number and reference a DT number.

Searched up the name and almost every single review of the place labels them as scammers who call about fake or already paid toll fines.

I don't have any toll fines, I don't even drive or own a car. So I can only assume they're trying to scam me as well by using the toll fines as like a common thing a lot of people will have so they're more willing to call back and pay fines they think they have.

They leave a message to call 1300 883 303 and to quote DT-******** . They want you to identify yourself before they disclose who they are. Didn't come down in last shower.

They leave a message to call 1300 883 303. They say it's important to call, quoting DT******** number.
They won't disclose who they are. Apparently you need to identify yourself before they proceed.
