no sound. kept calling

Keep getting calls from this number that just hangup

I got 5 calls from this number in one night, they said they were a utility company, definitely a scam,
Do yourself a favor and block the number.

rang back no answer and rung out

Caller: Some kind of energy supplier

Calling to make sure I'm not paying too much for electricity. Talked over me when I tried to tell him I'm at work and can't talk....seems to be the way of these kinds of callers so I just had to hang up.

I called back number (03) 4216 3000 rang 5 times then goes to busy tone.

Don’t waste your time answering. Call centre.
