Who called from 7203583004

I have received probably 5 calls a day from this number for the past several days.  Everytime I answer, all I hear is hold music!  When I called back, it said "Thank you for calling our sales department," and then more hold music!  Will call my phone company to block the number.

Same...same - Music and, then, someone saying my first name...
