Caller: Someone claiming to be doing research

This number called multiple times before I answered. They wouldn’t leave a message & when I tried to call the number got a recording saying the number isn’t connected.
Unsolicited call. Ask for my age & whether I was a home owner.
I loathe these types of calls so didn’t engage any further than that.
I have now blocked number.

National wealth cold call!

Called twice today. Second call they asked for personal information before telling me what the call was about. When I said I wouldn’t give out personal information over the phone the maker caller became aggressive and said ‘your loss’ before hanging up. Doesn’t sound legit.
