Usual short delay before a male voice with an Indian/Pakistani accent came on and asked to speak to Mr [my surname] and said his name was "Mark" and he was calling about the Federal government solar rebate scheme.
I gave him a loud blast from the referee's whistle I keep near the phone and hung up!
I am on the Do Not Call Register but that does not stop scammers and telemarketers and other dishonest fraudsters.
