Omg!!! Signed up a week ago got a $50 credit on account and for first day apparently $38.00 was used of power. I have no idea why the lady at customer service works here she couldnt explain why that was. My power company I was with wise power was better.. using 50 per week of power with 6 kids in a 4 bedroom house that was amazing. I wish I had never changed. I asked the door sales guy if i wanted to go back to wise within a week or 2 are there charges he replied no.. just to find out I have to pay $150 to leave.. Not HAPPY AT ALL
