Unknown caller calls saying she( being Indian ) belongs to the above call blocking department. knows lots of detail about my number but. tells me I can call block unwanted calls and marketing calls. I simply asked her twice whether I could block her number ( the above number) and she hung up. It would be nice if whatever company owns this number actually disconnects it because its being used by an overseas call centre. they obviously call the above number and it gets re routed to next available household on their list, by the way belongs to telstra. makes one wonder.
