Yes, they are from FieldForce from the NSW Government Home Power Saving Program, which I heard might end in 2-3 months. Called to make appointment regarding (free, government subsidized) a shower head replacement.

How the f#@%&* do they know my name and numbers Evirosaver they claims to be .Are they from government
agencies? I did not give them permission to call me.I hate these anoying bastards .

Tired of this number calling me also. 4 times today, 4 times yesterday.

Problem solved!  Have had the same number calling for several days and no message being left.  Like some of you, I called back and received an automated Optus (or it could have been Telstra) message.If you registered for a home health check on the Envirosaver website, that is who is calling you on this number - to make an appointment with you.Why they don't leave a message is beyond me!Anyway, please call them back on 1800 813 660 between 10-8.  I dealt with Keith Foster of Fieldforce at this number, they are in Sydney. (Reception confirmed the above number shows up on my mobile).  Website is www.fieldforce.net.au

(02) 8873 8300 has called me constantly without geting the hint, This Is My Private Mobile Phone Number. I Will Be Taking Them To The Cleaners........

After the 2nd missed call from this number i called back and got the invalid phone number tone...

Received a call from this number on my mobile which has a do not call placed on it. Call ended before I could reach my 'phone. Tried to call back and was unable to reach anyone.

(02) 8873 8300 has now called me several times on my mobile while I have been overseas typically at 0400 in morning.  Number is a real pain in neck as call costs are incurred when overseas

I'm 15 and they're calling my prepaid service. Who are they?
