Picked this up on my cell and it's Integrys trying to get you to switch from ComEd to their "deregulated" electric plan. Very persistent and won't take no for an answer so I finally hung up. I actually am a customer of the regulated arm of Integrys, so I got hooked into talking before I found out it's this scam.
I love these calls, good way to get aggression out...just play the game (5 minutes is all it takes)...just confuse the hell out of them.....they just hang up...
