Has called me twice, no idea what for, first time left a message about something and that interviewers will call me within the week, possibly scam/survey

Yes scam

Something on my voice mail about a survey, it's spam, won't stop calling. Don't answer, have blocked number but they tend to call from multiple ones

Yeah. This one's a scam.

Caller: (03) 9122 0926

Caller: was a Female Indian accent. Said she was doing research/survey for a Medical Hospital wanted to know who is in our household. I said I was off to work couldn’t talk. Than she said can I call u Friday or the weekend. She was very polite on the phone straight to the point. But I’m not familiar with surveys been conducted on weekends 😁 or maybe I’m getting Dementia …. Scam.

Rang out. Missed call message shows. Late call 7.30pm from interstate so suspect
Election survey or similar

Caller: Roy Morgan Research

Call me every night at 19:30 and say she want to conduct a survey for me for 30 mins. I asked her where she got my phone number and she didn't answer it clearly but she said she got it from my tutor. However I don't have a tutor… I think it's a scam
