Ethical Electric Ridiculous electric rate hike Washington DC

Part of my electricity started to be supplied by Ethical Electric back in September of 2014 because I checked some box in a postcard, signed that postcard and mailed it back. I now realized that I was tricked into thinking that my electricity would be coming from environmentally-friendly sources at the same rate as Pepco provides. Now I am stuck with huge electricity bills. There was no disclosure of variable rate or a locked-in rate if you sign up for one-year contract. I had no idea that there was such thing as a variable rate, which doubles the initial rate per kwh, until today after calling the company. My electricity bill is usually around $60 when I was with Pepco exclusively. In December 2014, after the 3rd month with Ethical Electric, my bill went up to $152. I paid the last month's bill thinking that maybe I need to use less electricity. Then for this month (Jan. 2015) bill, it went up to $205. The ridiculous part of it is that I was not even home for 10 days because I was out of town for the Christmas holidays from Dec. 24 to Jan. 2 and I had turned off and unplugged all my appliances and heater before leaving. However, the bill was even more than the previous month's. The rate went from $0.085 with Pepco to $0.12999 with Ethical Electric in November then to $0.144. I was appalled. When I spoke with a customer service representative this afternoon (2/10/15 around 3:45 pm), the lady told me that the rate increase is due to the variable energy rate and she cannot do anything about my bills. I had never heard of it until now and Ethical Electric used an unethical practice in which the "variable rate" is not disclosed or it is hidden fine prints. Ethical Electric abuses the fact that most customers will not check the fine prints (if existed) in the midst of being environmentally friendly. I found out that Ethical Electric's fraudulent billing practices are common after reading numerous BBB reports here and doing some Google search. I became another victim of their fraudulent practice.
