This was a saleslady/telemarketer from GE (alarm company), who asked for my wife by name.  When I asked who was calling, she went immediately into this fast script......I interrupted her and told her that it was an unsolicited telephone call and to NEVER call back again.  I have received calls from these idiots, now & then, for several years, trying to get our alarm monitoring account away from ADT.  I recently discovered that there is NO NEED to pay more than $14.95 per month for monitored alarm service, with NO contract.  ............ I blocked this number with my PRO CALL BLOCKER, so they will never be able to call me from that phone number again.  I also filed a formal, online complaint with the FCC.  If thousands & thousands do this, MAYBE they will figure out how to do something about this continuous, illegal invasion of privacy using a private, unlisted telephone number that is on the do-not-call list.
