Solar rebate pestering call

I called back number (07) 3555 7846 rang once then gets disconnected automatically.

Hung up immediately

Hung up on answer. Blocked

Caller: Someone using the number 35557846

This number called me and then hung up as soon as I said, "Hello". Very odd. Don't give identifying information to this caller.

Caller: Michael Russo

Asked if I was still considering solar or still undecided
Told him I'm got solar. Then he asked if my bills were under $300 per quarter, I said yes and he said no worries and said goodbye.

Hung up immediately after answering.

Put on the blacklist

Scammers

Me too on a landline. On my mobile Optus says phone number disconnected too.

They constantly call me asking for someone called carol fry and each time I say that I don’t know anyone with that name and they say the will take me off their calling list but evidently not because I continue to receive daily calls

Hung up immediately after answering

Missed call. Called back. Number disconnected.
