Been getting calls from (02) 8315 1787 every day for nearly 2 weeks. I don't answer because I don't know who it is. I get a msg to say they have left a voice msg but nothing! Finally today there is a garbles msg like the caller is talking to someone next to them - mentioned "10%" and "harder to get it over the phone". Finally she says "hello is Gayle there" and pretty much immediately hangs up. WHO IS THIS?
