rang, didn't leave message, suspected spam

Caller: Claiming to be NIB health insurance

I answered and there was a lag before they replied. The caller claimed to be calling in regards to “a recent correspondence you had with NIB” then proceeded to ask for my full name, date of birth and address. I asked if this was a survey and they said “I can’t disclose anything until I get your details”.

keep on calling but when gone silence when I answered.. blocked

I answered and just silence from the other end until I hung up

Called three times today when I did answer they quickly hung up

Caller: Some fuel car savings program

When I realised he was trying to sell me some fuel program, I hung up

Spam call, rang and then hang up

Same, called our business number, picked it up and promptly hung up. weird

Keeps ringing, 4 times in a few days, no messages left. Can hear a call center in the backround. Very bad scammers
