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.

  Do not appear to try and rip you off like many of the others.
So for so good.
Transfer was easy. Communications a little questionable .... status update never received but maybe because I reacted to soon. Otherwise A+
