Caller: No clue

I have a feeling someone on seek is selling my information because ever since I've started looking for jobs I've had so many spam calls including this one

I answered in 2 rings, hung up as soon as I answered

Caller: I don’t know

Answered and said nothing. Heard someone breathing then they hung up.

This number called my mobile at 8:40pm. They didnt leave a message.

Same, it stopped after 4 rings..a robot?

called me at 8pm, saying they are from a marketing agency, i hung up

Missed call. Called back, said it is a market research company.

Not sure
