getting calls from this number on my mobile and home phone. Several a week and at really odd times.

It is a Telstra partner marketing phone which is having trouble once it connects and won't allow return calls. I have notified Telstra on 125111 and they are having it stopped. Might take a couple of days so we shall see how it goes

I've just had 20 missed calls form this number. I also get a disconnected message when I call back.

I've just had 4 missed calls over the last 2 days from this number. I also get a disconnected message when I call back.How do you stop this from happening??

Yep , the text sent . I told them to well and truly .......

They have been calling my business phone about 5 times a day for the last few weeks. They listen to my spiel and then hang up, as soon as I try to call the number back it is always engaged (probably hassling everyone else in the country).
