My wife received a call from this number on her cell phone; two rings and a disconnect. 20 minutes later my cell phone rang; same number, same disconnect. An hour later our landline phone rang; same number, no one responded when I answered. When I tried to call it back, it would not ring. Spooky...like we were being stalked. It made us feel better to read the previous posts identifying it as a telemarketer/scam outfit.
We don't know anyone in Illinois and receive calls every day, usually with some title like service or duct service etc Why would I hire someone to drive over 2 hours when there are 30 right here in town? They all have the 312 prefix. Didn't answer, glad after reading these.
Chicago duct cleaning company has Google Psychics that somehow know that you searched anything to do with Central Air or Heating on the internet? The simple answer to ALL of these calls: OFF THE GRID!
