I have been getting several automated calls from china during the night, where they leave a message. So I have to pay to check my messages only to find a chinese automated message. Is there a way to block those types of calls? I imagine vodafone are making a bit of money off them as people check their messages. I really wish NZ telcos had a form of capcha system to show that a real person is calling, so these automated dialers from overseas couldn't call.
