Harassment caller from Sydney NSW, DON'T answer or return call...phone # shown is a cover?

Spoof caller. Scammers

Caller: Some lad from a Survey centre

When I asked where he got my number, he responed with "From your Mother" and hung up.

Says she's calling from a charity and has a few quick questions. When I said no, she promised it wouldn't take long, I said 'thanks, but I'm at work ......' ....before I could finish she hung up.

Rang but never left message, I won't bother ringing back.

No response when I answer. Calls frequently

Didn't speak when I answered!
