I have had a few missed calls from this number when i call back its disconnected...Sick of the calls..STOP THEM PLEASE

I have called the 1555 vodafone help line a few days ago without getting the problem fixed so i assume after reading the other comments, that would be who this call is from.

Just called back and gave them a genuine blasting, doubt they will call me again

This number keeps calling me, and the first time a friend answered and they wouldnt say who it was and now im not answering haha. Then why I call it back it says its disconnected..so strange.

this number keep on calling me and when i called this number not activated / disconnected. I dont wnt this number to becalled

I got a call from this number too and it was about new international plans from Optus.

What I am gathering though is the number is a marketing company that both Optus and Voda use. Working in the phone industry myself I know a lot of business such as these have numbers that cannot be called back, hence why people get engaged signal or a not connected message when they try to call back to see who it is.
