Caller: Energy Scam Call

Indian Call Centre about my Energy account

Caller: they said they were from amazon

Rubbish call - came up as being from australia.
Tried to say they were from amazon.
I hang up and immediately got another call from thailand

Happened today. Agree - dead air.

Scam call. Claiming they are calling from NBN.

Gotten 2 calls so far today and if they can’t leave a message I don’t call back or answer if they call again.

Answered, blank and hung up

Tried calling this number back, but just get a busy tone. It's a nuisance number.
