Called my cell phone and hung up when I answered.

had some one called from this number , never answered

I have the same thing happening as above, starting to become annoying, this is day three! And 4th call. And as above, won't answer/rings out when returning the call. 03 is normally a Victorian based area code. How do you block a number like this? Who is the carrier?

I've been getting calls from this number a few times too. But this is after a round of getting calls from (03) 8256 6799 with the same frequency and never leaving a message on my voicemail, have since found out it's telemarketers from Dodo.  I'm not from Victoria so I don't normally get calls from 03 numbers. I'm assuming it's the same people on this new number. I wish I never signed up with them, Dodo are so dodgy.

called but hang up and I tried to call back twice no answer

1/2/2011: Well ... Dodo customer service confirms that (03) 9001 5100 is their online application office number and that they do have my details in their system - but I never sent these to Dodo - I have never had anything to do with Dodo - they keep transferring us to other service customers - Dodo confirms they made the call to me but as response to an online applicaitn - they are promising to find out how the source email address of whomever started this - last thing I want is to be stalked or billed for things I know nothing about! - they promise to get a manager to get back to me tomorrow
