I rang once and got disconnected

Its a company that changes household water meters, JEMENA
They just called me and the meter I have is to old and has to be changed
This has happened to our building in the past
Should not be an issue

I received a call from (02) 6192 6241, the person claimed to be from Centra, the company which (supposedly) owns my water meter, & claimed it needed to be replaced. I asked where the caller was, she said Sydney, but Sydney numbers start 029...., whereas 0261 is a Canberra code. Scam, I think.

Received missed call and tried calling back a few times. Did not answer my call and reached voice mail

Likewise

I called back number (02) 6192 6241 reached voice mail but did not say for what company.
