Who called from 5083421630

I got a call that said Attleboro, MA .  Left no message.

Received a call to my business. Answered, no response from their end.

Caller ID said Attleboro MA  I ignored this call like most others.

I received a call from this number, wasn't home when they called.  When I listened to the message it was a very long dead silence message.  My number is blocked & on the do not call list.  I pay extra every month for the block number. . . . . a lot of good that does.  These callers need to get a life & get a REAL JOB!!!!!!

Picked up the phone. Dead air. Didn't wait for the robocall to start. Caller ID says Attleboro, MA.
