Got a call from this # too I am not sure if it is someone who is spoofing their # but when you call back it says that it has been disconnected.

Someone supposedly doing a survey on the quality of water in Cary IL.  Well water vs. City water and do I own a water softener.   The caller sounded like he was 12 years old.   I am guessing someone will follow up trying to sell me a water softener.   Le freak.

Received a call from this number twice in the last 3 days (Nov. 17th and 19th).  Both times I answered, and said "hello" several times, but their was no response on the other end of the line.

They call me at least 2-3 times a week, takes several "hellos" before they answer, ask for me by my first name..doing survey on water in area. If you answer the questions, you will eventually get a follow up call regarding a softener system, etc. I am on do not call list, yet they continue to call. When I try to tell them this, they end of hanging up on me. When doing a call back on this number it says it is no longer in service or disconnected.
