(03) 9637 6400 - This number is used by United Energy and could be their Customer Resolution Centre 1300 792 456.

has to be from a huge call centre i have rung several numbers from 9637 6400 to 9637 6435 and all just ring a few times then disconnect

had a call from this number regarding a query we lodged with United, should be customer service area. FYI if call back will cut out on third ring. Call the 1300 or 1800 number to contact back their pretty quick for an energy provider

Confirming it is United Energy Customer Centre

Yes we are also getting these call ( sometimes very late at night ) numbers that come up on the ID are (03) 9637 6400 & (03) 9655 0125

Called on my mobile, usually have no issue with telemarketers. Called Optus and was told that that it was a unlisted number so there was nothing they can do atm. but due to a number of complaints they are working to trace/find a way to block the numbers system wide.

they annoyed me today too. It was great to find your comments. Whoever it is, they are not important!

they seem to call every time i am not home, i see it on my caller id when i get home and its flashing i have rang them back to see who it is, but it just rings for a bit then just cuts off, i would really like to know who it is

Dropped out again and no response to a reply.

i have the same thing happen to me i find it on my phone everytime i leave the house, i would really like to know who it is, maybe its throw telstra or optus or dodo, who are you with im with dodo

Everytime i leave the house that number calls and i see it up on the id flashing, i would really like to know who it is, what are you house phone with coz it could be just throw the same company im with dodo

I have had the same thing for past 2 weeks and again today. Tried to call back and they hung up. Hope it's not surveillance. I'm with Telstra
