Well, I just called it and received a message advising that it was a NAB (National Australia Bank presumably) number.I do have a relationship with NAB so this could be correct. I wish they would just leave a message with a number for me to call them back on.Stupid big companies!

I have been getting 2 calls a day for the last 2 weeks !!!All calls come from  (03) 8330 4688. They dont leave a message. When i called back it was the same NAB message about "recently called you etc etc etc".I called up NAB on 132265 and said someone has been calling etc - they told me there was no record of any calls on my profile !! I am not happy and this is very much harrassment - if they want to speak to me so badly, bloody leave a message !!

HI GUYS !

I SUGGEST IF YOU WANT TO PREVENT THIS FROM HAPPENING , GO TO THE "DO NOT CALL REGISTER" ON THE AUSTRALIAN GOVERNMENT WEBSITE. JUST ENTER YOUR MOBILE PHONE NUMBER, EVEN YOUR HOME PHONE NUMBER IF YOU WANT.

From the time you register your number, it may take up to 30 days for individual telemarketing agencies to recognise your registration, and stop calling to your number.

Under the Do Not Call Register Act 2006, telemarketers can check their calling lists against the Do Not Call Register. If a telemarketer calls a number on the Do Not Call Register, they may be in breach of the Act, and may face penalties.
Thanks
Hope that helps

got a call from the number called em back to get a NAB answering machine about product and services.

This is getting tedious. (03) 8330 4688 doesn't seem to stop ringing us.

just missed a call from them. When I checked my voicemail it sounded like a female sighing cos i didnt answer. My parents told me the other day that they asked for me on the house phone.. and it was NAB.
