Who called from 9729246851

Sounds like a phishing scam to me - especially if they hang up when you answer.
Possibly confirming that you have a working phone number - a number that can be used or sold to another scammer.
We have the 972 area code blocked - we have/do no business in Texass.

Called ID said Anna.  Didn't answer phone & they left no message.

Calls everyday, appears to be the same woman each time who fakes a "stutter" and says "hh..hi, is the owner around by you". I just hang up.

Our 2nd call from the 972 area code today.  The first call was from 972 497-2928.
We have the entire 972 area code blocked.  Our phones do not ring and our office is not disturbed by their illegal and continuous calls.

called again today - blocked!
