Didnt answer but thanks to Marly who did answer, confirmed it is yet another solar rebate.
I did answer such a call some time ago and I lied about not having solar panels so the actual installer called me (I'm on the D.N.C. register but means nothing to gutless Telstra).
It almost got to the point their sales rep was going to come all the way up country to our home only to find I already had installed 42 panels myself.
I couldnt let that happen so confessed.
May someone else teach them a lesson please?
