Who called from 7203986207

Call several times a day. There is no one there when I answer. Number not in service when I call back.

They call several times per day and hang up if you answer.  "Not in service" if you call back.

I get multiple phone calls from this number each day and I am reporting it as an unwanted call.

6 calls today, spaced an hour and a half apart.  They're trying very hard to contact me, but never leave a message.  This is outright harassment.  An ethical firm would not do this.

They should hope that I never find out who they are.
