Who called from 9729246851

We have most of Texas and Florida area codes blocked and this is one of them.  I suspect that this is a google - "...your business has been flagged..." call.
The call was blocked and our phones did not ring.

Caller ID said "MERCH FINANCE"--only heard boileroom background noise, no one on the line.

Called office, answered w/co name, no response.  I hung up.

2 second delay prior to someone answering.  Background noise...assumed to be a "boiler room" call center.  Caller then hung up.

Calls and hangs up after I answer. Not sure why they want to waste their time but not easy for me to get to phone. Sad.
