Pick up then they hang up

RIng then hangs up when you answer

They were wanting to confirm answers to question which seems to be a scam . I just hung up on them.

Scam setup. I'd say they are using VOIP to make it look like an Australian number.

I answered the number & they had a lot of personal details of my wife, the female stated that they were from Fisher & Paykel Washing machine department.

The female got nasty when I started asking for her details, name, number & who she works for. But she said her name was Lisa Hayden.

Very concerning that she had a lot of details of my wife....

I picked up the call, said hello, and after a moment of nothing from their end, they just hung up.

I think this is a scam. I called back numerous times after they asked my name postcode and age. I hung up but they rang me back

I called back number (03) 9354 1405 rang 5 times then goes to busy tone.
