Have received numerous calls from this number. I have tried to call it back from work but it was answered then immediately hung up, as if done by computer, numerous times.

We recently changed phone service from Telstra to another provider after much dissatisfaction with Telstra and after filing a complaint. We kept getting calls on all our phones from this number. A long time after we had changed to another provider, when a Telstra customer service manager called to discuss our issues, I mentioned that we get many calls from this number. This Telstra customer service manager said that this is a Telstra number and it shows up on our phone (caller ID) when Telstra makes outbound calls.

Called both my pre-paid and plan phones. Did not answer. Tried phoning it back via a land line and just hangs up

Hi,  I've had numerous calls from this number which I've missed.  I too have tried to call back but the number drops out/hangs up.

This number is Telstra. They just called me to follow up on a phone survey they did after a customer service call I had with them a week ago.They wanted more info on why I rated their customer service as poor.The operator seemed pleasant and interested. Hope they take the comments on boardBaz

Have been tryeing for months to resolve a problem with Telstra. Cant talk to the same person twice. Have been waiting for a responce to a complaint and got two missed calls from (03) 8623 7900. Tryed ringing. Telstra faults sayes it is not a Telstra number.
