Originally I answered with Business name, they hung up.
when it called back again I just answered with "Hello, how can I help" and he said he was Looking for the "Business owner".
They called a single store that is part of a International (AU & NZ) company. "Owners" not onsite.

Have received many calls from this number. They never say anything, they just hang up.

I picked up and stayed silent, they terminated the call within a couple of seconds without sound
