I called back number (03) 9112 5942 rang once then gets disconnected automatically.

Wanted to know what power company I used.
Hung up on me when I interrupted the scripted speech with a few questions.

My number has been only connected for 2 days and I’ve already received 3 nuisance calls from this number. Don’t you parasites have anything better to do? Stop calling or I’ll report you harassment!

returned call, Optus message stating that the number i i have called has been disconnected.

Calls but does not talk

I did not check, but checks your site to check if this has been reported as spam, before checking with them

rang back and its disconnected... How do they do that?

Tried to call number back. Recording said number is not connected. Obviously scammers trying to sell something. BLOCK

I rang back and "Optus advises that this number is disconnected". So now I have blocked it.

Caller: Scam

Electricity bill

Caller: I DON'T KNOW - NO MESSAGE LEFT

RANG BACK AND NUMBER DISCONNECTED
