I said hello and they hung up straight away.

Solar Solutions calling on behalf of the federal and state govt wanting to know if I had solar panels. After asking him to repeat himself several times due to my barking dog he hung up.

Answered and they hung up

It will hang up once you answered.

Hung up immediately

Got the same as the last comment..answered hello and the call ended. After reading these comments, have blocked the number also.

Optus advises that this number has been disconnected...(despite just calling me seconds ago)

Received several calls from this number & I called back 3 times & instantly got the standard 'plz check the number & try again' message. Will block
