Caller: Possible scam

Claimed to be from Prime Wealth Advisory. Had my full name. I asked how they got my number and they said they're not allowed to cold call, and would only have my details because of previous investments or advice I've received from them. I said I've never heard of them and don't have any investments and they hung up on me mid sentence.

Thick accent and long delay between speaking makes me believe they were not calling from within Australia.
