Said they were a seniors health check. I played along for a while as she kept asking questions to be answered yes/no but I would answer I did or I don't and sometimes , as I had read before that you should not answer yes or no as they could be recording and use your voice for other things that require voice imprint, then told I have to go

Caller: Not sure

An Inian speaking accent man said hello & my name said he was from some health care organisation of sorts couldn't quite make it out, said have had complaints about health issues and asked how my health was, I said that was my business not yours and hung up.
I'm very cautious about a lot of calls these days, however looking back at the phone number it said It was 02 for NSW, so out of curiosity I rang the number back ... It answered with a recorded message saying about leaving a message and the openibg hours intime zones of UK, Sydney, Singapore, Canada, and so on over the world, but no name of company, but you can happily leave your name and number for a call back ... so I am 99% sure it's no genuine health enquiry call, but one thing I never give out any information health or otherwise, and don't recommend anyone does.

A male Indian voice saying he was it was a seniors health check. I hung up.
