Just got a letter stating that Direct Energy just dicovered a processing error in our monthly water heater rental rate. So our December bill will include the difference between 2009 and 2010 rental rates. BUT I should be happy because they are taking steps to make sure it does not happen again.!! Also no indication of the amount they will be billing. Evidently 25000 people are affected. They should suck it up it is their mistake Plus the notice came after the billing went into effect. read full review »
