Easy to use!

Love this app - fixed all the bugs and VERY easy to navigate now. I can log on with Touch ID so I don’t have to remember user name and password. I can check my usage, my expiration date, even my full pdf bill - which I was impressed with. Way to go Reliant!

Problematic application

While this application is great to review your energy usage and pay your bill, I find that there are a lot of bugs using this application on the iPhone operating system. Almost every time I open up the app and login, I get an error message saying the site is down for maintenance when they are not. I am forced to completely close down the app and from running in the background well attempting to open it and login once more before it will actually let me into the site to review any information. I have noticed that I receive constant notifications once logged in informing me that my last months energy usage was higher than the previous months when this is not accurate and every time I ignore or close the message it always returns.

Horrible app

This app is no bueno ! The other day I had to pay my bill so I did it through the Reliant app. I payed the amount I was suppose to pay and out of no were it processed TWICE !!! Making me pay double.
I went to my bank to claim this and I got my money back, and RELIANT took it back again and also took $11 u don’t know why but this freaking app did it.
I called them to make a concern about my money and there app and they told me I needed service calling me old but I am 28 ! I know how technology works and everything but this app sucked and I had to pay them back no matter what.
