calling 'about my electricity ' 😒

could be iselect. ok if you want to change supplier but annoying if you don't.

Rang 30 June I missed the call but looks like this number is spam. From above comments.

Call back but number disconnected

Called back. Automated voice said the number is not connected.

Spam

Another pointless brain dead telemarketer

I phoned the number back but my Optus said that the number is disconnected please make sure u have diled the number correctly it's not the first time this number has called me

They called me. I was quick to pick up, and they hung up. Call back scam?
