call and ask for person and then hang up- they do not identify themselves

the very gentle sounding woman (i'd guess to be in her 50's) identified herself as calling the Gladstone Group and wanted me to take a survey on live family entertainment.. i said ok.. and as the questions became more and more personal, i decided to stop... first they asked zip code, asked if i had kids under 18, what major city (from list) i was closest to, and then the age groups of each child... at this point, i very politely said "i'm really not comfortable with this survey anymore.  could you please take me off your list?" to which the only response was a LOUD hanging up of the receiver on the caller's end.  VERY UNPROFESSIONAL... I don't know what their deal is, but I do not think they are legit from this experience.

I have not answered, but they keep calling everyday.

They keep calling us 1 to 2 times a day...every day. We just don't answer.

Just received a call from some lady saying she was from the Blackstone Group and wanted to do a survey on hospitals.  Strange!  Anyway, I told her my phone number is on the Do Not Call registry and she replied saying they are not selling anything, therefore do not have to abide by that list.  So I asked her to put me on their personal do not call list.  She said she'd see what she can do.  Sounds like crap to me!
