Missed call from unknown number. No message left so blocked

I was called by this number , I said Hello and they hung up . I didn't speak to anyone.

Caller: (02) 8530 8828

about to answer the call then it hung up. Must be a scam call or telemarketer.

Pretended to be ‘An important Government Department’ then transferred me to a Mandarin speaker so I have no clue what it was about but the govt doesn’t use telemarketing bots or even call you direct for anything.

Caller: DIGITAL DESIGN COMPANY lies

DIGITAL DESIGN COMPANY FOR WEB DEVELOPMENT they say if you call it a computer and there no support team it just repeats it's self and if ya press 1 it says there busy and hangs up

I don't have ay contacts in NSW (02) and as no message was left, I have blocked this number.

Caller tried to tell me I had enquired about a low interest loan with them, said the company name so fast (twice) that it was incomprehensible. I have made no such enquiry and I told her as much telling her she was a liar and a scammer. She hung up.
