Who called from 7012040971

This call came in for my recently turned 18 year old son who is still in school by the way.  Says it came from Bismarck, ND.  The guy asked for him and when I said he wasn't and whether I could take a message or not, he just said "nope" and hung up.  I called him back from a "dummy" phone I use and it stated that it was a survey call and why wouldn't you want to be surveyed.  I am on the do not call list for our land line they called on.  You can stick Mr. Caller!!!!!!!!!!

They keep calling. Never leave a message.  Just got out of hospital and trying to rest.  We are on "do not call list"  and annoying as ****

The last two nights I have been getting this call, when I answer they hang up!

This number calls every night during the week at dinner time and 3x a day on weekends.  I simply hang up without answering.
