If it's about changing your electrical supplier, then it is NOT a scam. Your state's utility commission has strict rules and any change must ultimately come from your regular electricity distribution company.
In addition, electrical supply companies are not affected by the "do not call" list. They are allowed to call you because of your connection with your electricity distribution company.
If you get a call, answer it and tell them to take you off the list (unless of course you wish to accept their offer, which is worth exploring). If they do not, then complain to your state's utilities commission, which will enforce your demand.
I happen to be familiar with electricity supply companies. For more info, go to your state's website and find the link to your state's utility governing authority.
Obama and the democrats are behind all this, desparate people do desparate things. Just like the USSR back in the 50 and 60 this was done to the people! Way to go Obama!
