Citizens Choice energy Big mistake of switching electricity supplier. Teaneck, New Jersey

In May, 2012, I received a call from a sales person that I would save money if I switch the electricity supplier from Con Ed to Citizens Choice Energy. But the rate of Citizens Choice was much higher than I was told by sales person, even higher than ConEd on last three months bills and I called to complain. It is true that sales call was not made directly by Citizens Choice. It was by Discount Center and I agreed even after I was told that the rate is variable but higher than Con ed?  A supervisor of Citizens Choice said that they never advertise that they are cheaper than ConEd and  " I don't know" when I asked him why would people change the supplier other than to save money.
