Caller: female caller

When I answered there was a delay of several seconds, then a female caller with what sounded like a Filipino accent (and background noise of a call centre) told me that her name was Julie and she was calling regarding the government rebate for solar panels. A few minutes later I had a second call (from the same number), this time from a woman (also Filipino, I think) who said her name was Ellie and started asking me the same questions as the previous caller. In both cases I simply told them that I was in credit and didn't need to modify my plan. I strongly suspect they were both scam attempts, especially since I had an almost identical experience (two callers from the same number) the previous day. In any case they are certainly a nuisance!

Caller: Idiotic Scammers

Some crappy indian call centre representing Australian Solar mob to sell you fake solar panels.

So avoid like the plague!
