I called back number (02) 9046 5600 spoke to a woman who said company name is Lonergan Research.

Caller: Scam operating from our number

I am the CEO of Lonergan Research. Please be advised that criminals are using our number for a scam. They are either encouraging people to sign up for a mystery shop where you are asked to buy and sell bitcoin or other crypto-currency, or asking people to take part in a survey about savings and investments.

Be advised that although we do mystery shopping and research, we do not ever work in crypto-currency, and the lifetime investment survey is not ours. We are not making these calls. We know that a huge volume of calls are being made with our number on the caller ID (presumably a power-dialler of some type).

We have informed ACMA and the AFP. Please contact our office if you have any queries - (02) 9046 5600 is currently offline (as of 31/5/19 - due to the huge volume of calls), but our telco is working on a solution now. We should have it back online over the weekend.

Apparently from SurveyHub wanting to send a consultant for my opinion on a product at 6-8pm for $50 at my house... I don't think so!
