When I answered there was nobody there & then they hung up

I answered and there was no one there says from Tamworth NSW

Came up as Tamworth NSW - two rings then stopped - no message left.
Note: Text message rx from 0481 075 318 yesterday - advising they were Social Research Centre and would be in contact - option to opt out given but had not done so. Google search shows Centre is under auspices of University ??

Had (02) 5732 5749 called me twice (both missed calls) seems like it’s a survey thing. But has others also received calls from 0425 071 206?

Caller: losers

Call from (02) 5732 5749 The woman said she is from 'The Social Research Centre' doing a survey. I just put the phone down without hanging up LOL! After about 2 minutes the woman rang back and I didn't answer it haha! Blocked and deleted.
Note I also got a SMS the day before from a different number (I deleted it) telling me they would call LOL!

Caller: Research centre

Claims they were a research centre asking about the sexual health of women aged 16-59 , told them to remove me as Im on the DNR register and ph number is silent, they then pushed and said call another time, was an hour before dinner time -_-

From Tamworth.. I didn't answer !

c*nts

Caller: Advised calling University research centre

When asked where they collected my number they went silent, ended call, sounds like a scam, avoid

I had 4 missed calls from this number tonight, so thought I’d call back in case it was important. It’s ‘The Social Research Centre’, no doubt trying to get lots of personal details.
