I called back number 0451 100 170 rang once then gets disconnected automatically.

Phone rings a few times, then stops whilst I'm still deciding not to answer.
Came here to check it out. Received notification yesterday that an outstanding Energy Australia debt had been "sold" to Impact debt collectors. So with the information obtained here and the notification received yesterday, I'm absolutely certain there's a definite possibility that the unknown caller just might be Impact debt collection, and I would not hesitate in saying that. I'm confident there's a very good chance

debt collectors

i keep getting calls from these mobile numbers they are as follows 0451 173 224 0451 100 170 and 0424 511 900. they do not give me enough time to answer my mobile and they do not leave any message or say what company they are from.

Its impact financial services.... They are debt collectors.

This number rings and then hangs up not giving me enough time to answer and doesn't leave voicemail so not sure who it is as I've never given out my number
