Don't know anyone in Taree! No voicemail or text left on mobile phone.

Caller: Finnway Energy

I received a missed call from this number, which appeared to be from the Taree area. When I returned the call, I was greeted by a robotic recorded message from “Finnway Energy,” instructing me not to hang up and that an operator would be with me shortly.
This kind of call was unsolicited, and there was no prior contact or reason for a company like this to have my number.

Called similar time tonight as yesterday’s call from (02) 9561 9594. Similar area number. Taree NSW. Coincidence?
No message left.
Blocked, same as (02) 9561 9594.

Comes up saying it from Taree. I answer but don't say anything and then you just get an automated message that says "goodbye".
