Scam. They've been calling nonstop for two days on personal phone and landline.

Political survey call. Person had Aussie accent (seemingly, not an overseas call centre). Knew the law regarding the do not call register (political surveys are exempt). Probably not a scam.

I don't know who this was but can tell you that no one who butts into my home uninvited just after 9.30 on a Sunday morning will be speaking to me. Not that I ever answer calls from unknown numbers these days in any case ...

Caller stated he was from a research co on behalf of Melb City Council. When I stated I was not interested, he got really aggressive and screamed DO NOT HANG UP. I still hung up hahaha.

Caller: Robert (claims to be from ACMA)Robert, who claims to work for the 'telecommunications department'(or some such) of ACMA*, rang asking how many nuisance calls I get on average. Told me they have a new system that will 'stop all telemarketing calls' and 'wouldn't cost me a penny'. Trying to imply that they were working on enhancing the 'do not call' register. Hung up when I asked why, when I'm on that register, they are calling me?? *ACMA are a legit Federal government department - home page https://www.acma.gov.au/ . But calling at 6:45 pm???

Caller: Said they were from a research calls centre from a council I live in over 4 years ago. Just annoying. So best just to block them. Said they were doing market research for my local council but I hadn't lived in that council areasm for almost 4 years so they hung up. Best just to block and ignore. They did know my correct name. Block listed. Done.

How is it any bloody different! As far as I’m concerned their still nuisance calls wasting our time to do surveys helping out companies free of charge.. I find surveys almost as annoying as any other spam call..

Caller: Market ReasearchThis is a genuine number calling on behalf of various companies for market research. I know this because my company uses them. I wish so many reporters would not jump to marking calls as a scam when it was just an unsolicited caller if they don't want to complete the survey.

No message left. Have I missed out on an inheritance, again! :-)

Caller: No ideaThey call very briefly almost before you can answer. Very wary now if not in contacts list. If it is urgent, genuine callers will call again. Otherwise, as others have noted, it is a scam or marketing. Calling around dinner time is another give away.
