this was by far the most expensive service I've used.
The service is great!
So far, frontier utilities hasn't given me any problems. My issue is with the pricing- I'm a first time apartment renter and didn't do enough research on the pricing of kwh's. Smart City offered to take care of the utilities sign up, but somehow got me a contract that was almost 50% higher pricing than the contract I would get if I had signed up directly with Frontier. And now I'm locked in for over a year of this pricing. Not fun.
So far we've been pleased with Frontier since we started service in December 2016. They're web portal has some good metrics. Waiting till the end of summer to give a full review.
