I have been with Dynowatt for approx. 3 years and have been totally happy.
I have saved a ton of money dumping TXU. I was a little scared of Dynowatt because I had read some complaints about poor service and price gouging. Well they finally got around to sticking it to me. I have been paying .108 cents per kwh for many months now and I just got my August 2011 bill.
They charged me .185 cents per kwh. Thats a 72% increase in one month. That would be like gasoline going from $3.00 a gal. to $5.16 a gal.
in one month.
I havent called them yet but I expect I will be changing provider again. I dont do business with crooks!
