I called this number back.  Sez it's not in service and I got the sound for disconnection.

Heartland Financial Group. They sell Health Care and other insurance related products.

Received first call at 10:45 and politely asked to be removed from contact list.  Received 2nd call about 10 minutes later, repeated request and hung up.  They have now called 15 times in 10 minutes.  I called their home office and receptionist was less than helpful so I called back after finding names of CEO, CFO, and VP's. Left voiuce mail for VP and expect call back before end of day

Business owner is Aaron Sims.  His email is asims@e-hfg.com, his other email is asims@aviantfinancial.com.  Called me more than 40 times in one 2 hour period and then says he will take my name off contact list.  I have filed charges against him

Why not name names? Turnabout is fair play. With enough sleuthing, 1000s of people could now be calling CEO, CFO, etc at their own homes and cells
