I never signed up for direct energy, but I used to work for a consulting company that did the door to door soliciting for them.They trained us to lie to the customers and make them feel like they need to sign up for the fixed rate.
However, after looking at a lot of customers bills, Direct Energy wants to fix the rates at usually double at what the customers are already paying. I would never sign up for this personally because you are locking your self in for 18-22 months in a contract that has a $99 cancellation fee.
It isn't worth it to sign up for this service.I suggest keeping your SCO variable rate.
Reason of review: Bad quality.
Preferred solution: Let the company propose a solution.
