Easy

(4.8 / 5)

  I signed up for a six month plan and everything went smooth. Connection, (online) billing and payment, and disconnection when I moved out all went smooth and without surprises. I had great service every time I called customer service. They didn't have the best price, but I would rather pay an extra cent/kwH than have to deal with incompetence.

Happy Customer

(4.8 / 5)

  Startex power was great. I used them last few years and ended 12/2015. I rated them 4 lamps because I was billed an early termination fee that was supposed to be waived since I moved. I spoke to 3 different Customer service reps about it and I was told all was good every time until the next rep would call to get a $49.50 payment. I just received a call from a collections agency, claiming I owed the $49.50 again and told her the story. She told me to email her the Info. I called Startex Power, spoke to another kind service rep,( they have all been kind and helpful), told him what was going on, like so many times before and he said he sees all the notes but that the cancel refill had not ever been filed. He was doing it now and they actually owe me 50 cents since I over paid my last bill. So they were a good company I used for years until I moved in with my fianc. I would still use them but he has a contract With another provider.

unable to change plan

(4.8 / 5)

  Historically happy StarTex Power customer, but received current bill. Last month we went over in usuage: 5297 kWh. Last year we only went above 2000 twice. Bill was very high. Called hoping something could be worked out, I even asked for any suggestions. Only suggestion was watch a tape on how to use electricity, ouch! Looks like I will have to change companies to save money. I wish they could have offered something.

Great Service!

(4.7 / 5)

  I like the customer service that I receive from this provider. I have had two other companies and this is a step above them. Not much that you can say about utility companies, except how much they drain your wallet. But StarTex gives you ease of payment options (no service charges for Visa/MC) and great customer service.

So far so good.

(4.6 / 5)

  Switched providers because the old supplier had rates that were no longer competitive. There was a brief glitch during sign up. Ultimately, the old account was shut down, and the bill was issued with competitive rates.

A little confusion. Easily cleared up.

(4.6 / 5)

  Upon getting what I thought was first bill it had an inappropriate rate assigned to it. Called customer service and was explained meter reading date was the issue. Subsequent bill was correct.

  I have only been with Constellation for a month, so it remains how Constellation will be for the rest of the year. But so far, my experience has been very positive.
