Had a missed call from this number I ring it back and it was disconnected it is an Optus number

Don't pick up, someone wanting to do a 1 minute questionnaire. Waste of time

Same ... no one talking and then hang up

silence and they hang up.

hey OPTUS what are you doing this number is disconnected
this not the first time that OPTUS allows this to happen OPTUS YOU ARE A BUNCH OF sh*t!!!!!!

I have just got a call from this number and she asked me if I have any children at school. I said yes and I asked her why she asked me this and where she get my mobile number. She was quite angry and hang up

Survey

Apparently 'Better Solutions Australia' has my phone number, asked to make it On Do Not Call list.

Same as above , rung and I answered , then hung up, I returned call to be told it's disconnected ???

A couple of missed calls and two which I answered over the past month. Never any response when I answered.

Survey

Same as above. Very strange.

Same experience as Laurence. Missed call from this number, no message left. On returning the call I received the Optus message that the number wasn't available and error no. 06CCM29.

Not sure who this is. A co-worker and I both had calls from this number but no-one speaks - just silence on the line. Upon ringing the number we get an Optus message advising the number has been disconnected and quoting error no. 06CCM29.

Seems a bit fishy.
