The number called me, and I answered and heard background noise with no one speaking. The number is invalid is you try to call it back.

I was called, but the line was silent. Nobody spoke. add this number into auto reject list.

Called, answered, hung up immediately ... blocked

Kepp reciving call from this number when i receive call they will hang up idiot seriously every day and no one answering. Don't you have anything to do wasting time. I called back number (02) 4331 3800 just kept on ringing no one answered get lost

anoying

Got call but did not answer. As soon as I call the number back, it was Optus advising saying line is disconnected. It must be somebody who knew that number is disconnected and is using it to track people. Definitely a scam, maybe prank, but can be a criminal.

I just had this number ring and hang up ovrr 5 times today. The number is disconnected when I try calling it back. Definitely a scam.

This number calls my mobile EVERYDAY. When I answer saying hello, they just hang up not saying a word. I have tried to call it back and its not a connected number.
WTF !!!!

Missed call from (02) 4331 3800 to my mobile. When I called back received message "Optus advises that the number you called is disconnected"
As has already been asked - HOW CAN THEY CALL FROM A DISCONNECTED NUMBER?? and how did they get my mobile no when I have only had it for a week??

I've been getting calls from this number & I've told them to put me on to their DO NOT CALL list, but it still continues to call me.

I've been getting several phone calls from this number for the last few weeks. I'm currently job hunting so I keep thinking someone is calling me back for an interview, so disappointing every time to get these same people taking up my phone time.
I've asked them not to call again but they still persist!

This phone (02) 4331 3800 rang my phone and my wife's phone at exactly the same time so I know its a scam. Didn't leave any message on either phone.

It is probably Promaster pest control. They are very shonky. Commonly target the elderly and don't take no for an answer. I just missed a call from them after having told them to never call me again.

a guy rang stating he was a guy giving a discount on termite treatment. whta the hell can you stop!!! its my 10th phone call

just called us and its offering terminate inspection, special cheap rates !!!!

I called back number (02) 4331 3800 just kept on ringing no one answered the call and never got any voice mail.

unable to call them back; typical marketer

this number just called my landline (i didnt answer) it then called my mobile number !
very suspicious as it is a disconnected number.......
who is doing something dodgy i wonder???

I rang this number back and was told it was a disconnect. The '43' suggests that it's in the Gosford area. How can someone ring from a disconnected number ??

I keep getting call from this number. When I try to call this number back either get busy tone or a message "the number your are calling is not connected".
