Time to make Caller ID available on all phones without extra charge. Yes some Phone companies still think it is an optional extra.
Then we can block the buggers ourselves.
Oh for a device that will actually answer a call from a blocked number and send a 110dB whistle down the line. Sort of like a Dog whistle. Probably illegal here though so it is just wishful thinking. But it might be nice to give something back to those so called 'survey scammers'.
