I get 3 calls per day from (02) 7259 0133 or similar numbers. I never answer and they do not leave messages. The other numbers are (02) 7259 0969, (02) 7259 0471, (02) 7259 0776, (02) 7259 0824, (02) 7259 0418, (02) 7259 0119, (02) 7259 0822, (02) 7259 0641. I have blocked them all

They keep ringing every few days. As I have an answering machine, they leave no message.
