Has called 4 times in last few days. I have not been home to answer and now I shall not bother.

Indian sounding caller wanting to tell me that the Australian Federal Gov has some rebates for Solar Panels.

Called from this and they hung up.
I called back and got a "the number you have called is not connected...", likely copied from Telstra.
I had a call on (03) 6121 4129 almost exactly 1 hour earlier from "Daniel", supposedly representing Prosecutions on behalf of Taxation Department.
He hug u when I told him their scam was well publicised.
