I called back number (07) 5609 8474 reached voice mail but did not say for what company.

Once a day for a week. No message ever left

Gold Coast number, no doubt a scam, called twice in two days never leaves a message. dodgy as I reckon

I got a crackly / bad reception voice I said “hello??” at least 3 times then I hung up. I rang back 5 mins later and got an auto voice message not saying who’s number it was just “at the tone leave your message”. Seems suss.
