missed call from unknown user. they can call again, I won't call back

Interstate call so with the time difference probably not a business call. Didn't leave a message.

National study on “television programming” voicemail 😤

They called me and i answered. When i listened into the phone, a lady repeated "Hello?" a few times, and in the background it sounded like there were other people, possibly even a party. The call is stated to be from Sydney, New South Wales, and im in Melbourne

Caller: Kanter

Rang and left a message. Said "marian from Kanter Tv ratings"

Called at 8pm, rang twice and stopped. Guessing spam or scam.

Missed call, no message left, identified by phone as suspected spam. Blocked

Unknown number. Did not leave a message. Why? Something to hide? Has to be a scam caller or prank. If you have nothing to hide and are genuine, why not leave a message, so we can call you back.

I answered the phone and they hung up immediately. Bit suspicious there.

Someone saying theyre collective TV data? But asks a bunch of questions about every device you own in your house, and what's connected to the internet. Bit sus to be honest.

Caller: I don't know

Stop calling people interstate who don't know you.
