I have had 2 calls from them too both at 1.13pm - I didnt answer the first one the second one I didn't speak - was a male on the phone. I am in New Zealand too.
This caller asked to speak to "any adult" at this number. I asked them how they got my number & what did they want? He said he was calling people in California about stuff having to do with the residents of California & could I answer some questions? I said I did not request this call & to take my number off of any list they have, then I hung up.
I've also been receiving repeated calls from this number and have not answered them. Next time they call I will answer and tell them I'm reporting them as my number is on the do-not-call list. How annoying that this is to my mobile number.
