"Todd with GE Security" keeps calls my cell phone nearly daily even though I told him the first time to stop. I block his number (this one now!) and then he calls from another. I'm tired of it!
Trips to the Bahamas and security systems from the same number? This character has it all, but he continues to call since he knows your number is known for having an answer. Change that by letting your phone ring if you can. Tire him of calling a number where the phone only rings.
