Solar company from facebook

Keeps calling, never leaves a message

Claimed to be a online prize but was asking for financial details and number of persons in home.
Got super defensive when I pointed out that i never entered what they claimed i enteres and that i thought they were a scam
Claimed to be a company called Beryl Lewis

Whenever I answer there's no-one on the other end. This number keeps trying to call me, most afternoons and early evenings. Very annoying!

They called saying I entered a competition to win an iPhone and $1000.
I did not enter any such competition with coles or woolworths.

Caller: Not clear

Saying I completed an online survey and still not sure what they wanted did not answer my questions clearly.

I returned a call from 0488 823 905 but no one answered the call
