I have been getting a number of different 02 phone numbers calling me for days. Just received one from this number today. I didn't answer.

spam

Caller: I think they are the result of a fake google survey

I received a pop up,"Congratulations you've won an ipad"
Your 1 of 10 selected Google users every Wednesday.
I pressed the YES prompt to accept the prize.
Started to answer a google question, followed by loads of promotional questions from various prominent brands. once the Branded questions commenced I answered no to all questions. I'm assuming this is it, they haven't stopped ringing for 3 weeks, I don't answer and have now blocked.

keeps calling

They have been calling me at least 2 times a week for the past month, they don’t have my first name cause they say it’s “John”. P.s: it’s not John

Caller: CCI or something the Indian accent said

Some competition place sounds like a scam, if you ask me

Caller: Crowded noisy call centre or office

I just got called. Background is very noisy at their end like you get from a crowded call centre. They knew my first name. They could not hear me answering because my mobile's microphone is very feint at present (some software setting fault I think). They hung up after saying a couple of "Hello is that Keith?" - female, mildly foreign sounding. Number (02) 6100 5365 likely to be Canberra or near says https://www.reverseau.com/(02) 6100 5365.html#comments

Caller: BRANDS OF CHOICE FROM CCI.
