Robo caller........   again, and again, and again,   it's been switching "caller id" numbers all morning,   most from  "Silver Spring, Maryland" ,  if you look them up.    Don't bother with ANY 240-535-xxxx number.....  That'll kill most of   ATT, Verizon  cell phone callers,  and then MAYBE ATT, & Verizon will do something about the robocalls.       HIT THEM IN THE POCKETBOOKS.
