I screen my calls and don't pick up if it is an unfamiliar number. Nuisance call phones but no message left.

Persistent people. Doesn't matter how many times they are to.d to disappear, it does not seem to be getting through.

Supposed to be Telstra calling from Sydney (with 03 prefix????). Asked address and they quickly gave a Sydney street address and also answered how the weather was there. When asked from what number they were calling they gave a 1800 number. Both this number and the number that showed up with caller ID when rung advised they that were not connected. Must be using a piece of string?
