Initial signup w/Constellation

(5 / 5)

  Using GeorgiaGasSavings is simple & convenient. I had all info I needed in one place to make the switch from our current provider once we realized they weren't trying to keep their existing customer happy. I've had nothing but positive experience w/Constellation in these first couple months.

Still Happy After Switching

  Marvelous experience and I'm saving money. Finally got the first bill to compare to the old marketer. Exact same charges except the Therm rate is no less which means I'm saving money by switching.

ABOVE AND BEYOND

(5 / 5)

  So far, I am pleasantly surprised with the consistency of the pricing, the weekly notices of how much electricity I have used compared to the week before and the estimated current bill.
It is nice to have that kind of detail where you don't end up shocked at the end of the billing cycle.
