Caller: Scammers

This week the scam calls from "internet service" are coming from the 03 area code (last week it was the 02 area code. Apparently there is a problem with my internet service blah blah blah...money needs to change hands....blah blah blah. Complete scam. I've noticed if I don't answer the calls with a displayed number, then the next few calls are from "private caller", but it's always the same thing - a problem with my internet and I need to pay money immediately or my service will be cut.
