Sometimes its a private listing but this time it had the number displayed

This number is calling me every day!

It is also pestering my partner.....
Can it be locked out?

Update (apologies, it's all a bit long winded):I registered my complaint with the Telecommunications Ombudsman, who gave me a reference number to follow up with Telstra. The Telstra guy was very helpful; he removed the call costs incurred for me pursuing the matter with them (and it turns out that there were no charges for me calling the Perth no. as the calls mustn't have registered?). But my main issue was that the complaint went through to the rude sales/marketing person in Perth and they were reprimanded for their rudeness and lack of professionalism, plus that their aggressive/borderline harassment phone call tactics were addressed at the managerial level. Whilst the Telstra Ombudsman complaints section can't give me details of the actual marketing unit responsible so i could contact them directly, I feel satisfied that they are going to address their tactics directly - hopefully. I guess time will tell... If there are any more complaints on this website about them, I'd suggest you contact the telephone ombudsman, get a complaint reference and then contact Telstra with the number and reference the ombudsman gives you. A bit time consuming but they need to know how sh*teous these tactics are so they can do something about them.

Have just spoken with Telstra and they have advised that it is a telemarketing number that is on the Telstra service and they have a spreadsheet that you can add your number to so that you can block this number from calling you.

They have also given me a 1300 number that you can block all telemarketing calls - 1300 792 958

yes this number has just started calling me a couple/4 times a week, so annoy you answer and they hang up, tired to call back and no luck it didn't ring, looked at the screen and it just went straight to disconnect
