I called back number (08) 9300 4374 rang once then gets disconnected automatically.

Caller: “Gas company”

Had two missed calls so returned the call. Message from Optus saying the number had been disconnected. Got another call some hours later and was a lady trying to scam saying she was from a gas company which we don’t use and that our bill was overdue.

8th time this week that this or similiar number has phoned me. No message left and don’t speak if answered.
4-6 seconds in duration

Have been receiving this number for few days. Tried picking up, and it hung off immediately. I have blocked the number.
