I have been receiving call from (03) 9655 0100  and (03) 9655 0123 for a month now, I either miss the call and try to phone back but the number does not respond, at one time I answered and they hung up, it has left me feeling qwuit anxious as I had no idea who was harassing me. I think the number is connected to Red energy, I rang them but they kept me on the phone for so long I had to hang up twice in the one day, at the moment I am again waiting so far over 20 minutes and still waiting.

Hey All,I have the answer. Its Red Energy phone number - www.redenergy.com.au. I had the same issue where I missed their call before and could not call them back either. This time I got the call.Pretty crap that a company of this size would show you their caller ID, especially if you cannot call it back.

It's Red Energy trying to sell you their product.

they called me and started the call with "Hi. Are you aware of the rising costs in electricity and gas prices?"

Just reply saying, "no - i live in a cave. thank you & goodbye."

they called me, left no message, i tried calling it back and it's as if they just reject the call. not sure who it is.

Hung up on my answering machine.

Copy the number to your reject list on your Phone, and annoy them back!(As soon as it rings the phone rejects the call)
