“  Having just moved to Waco,TX from Pennsylvania, we had nothing to use a a baseline to compare electricity providers. We picked Constellation based solely on reviews. After 7 weeks, so far so good. A better assessment and review will need t owait until we've been here a full year. ”

Hate to switch

(4 / 5)

“  I was on a rate plan until this July and was very happy. I did not enter another because I knew I would be buying a home and was worried about breaking a contract. Even though I have been going month to month my bill has been good. Unfortunately I am forced to shop for another company because the new rate plans are very high. I have not had any issues, I love that I can go online and pay, and my bills were decent. They no longer offer any rate plans that are priced decent. I did try to call customer service to see if I could get a lower rate as a loyal customer but no luck.....so I will shop and read reviews until I find another company ”

You Had Me at Customer Service

(4 / 5)

“  Been with StarTex Power for a couple years and at the end of current contract period. While there are some other companies with slightly cheaper rates, I was drawn back to renew my contract by the excellent customer service, no hidden fees, and no gimmicks (like paying $5.95 to call Customer Service . . . *cough*- Reliant-*cough*). I'm willing to pay a little more for a company that exhibits integrity in dealing with their customers. ”

Hate to leave...

(4 / 5)

“  We have been with StarTex for about 1 year now. We really love the wonderful customer service and excellent service. We recently received our renewal notice and unfortunately we may have to switch companies. The rate we were quoted is not as good as the current offer and are not as competitive as other companies. We would really love to stay but have to do what is best for us. Thanks StarTex for making our transition to Texas a great experience! ”

It's Time To Move On

(4 / 5)

“  I've been a Star Tex customer for 3 years, and I would have to say had a good experience with them up until now. After the first year, they notified me that my contract was up for renewal. I requested them to renew at a certain rate, which would have been comparable to one of their competitors. They agreed, and all was well. I was in for a surprise when that contract expired. No notice, and just a surprise bill with the rate jacked up 3 cents KWH. I sent Star Tex an email asking if they would lock in a lower rate, letting them know that if they did I would refer a customer to them. I received a big N-O, and that was the end of that. I then requested a letter of credit from them, and haven't heard anything back. Needless to say, it's time to switch, because my monthly electricity bill is way too high, and they are simply no longer competitive. ”

Contract Renewal

(4 / 5)

“  StarTex has always been a good company in the four years that I have been with them. When it came time to renew my contract, customer service tried to work with me on my rates and could only offer me a nine months contract ( I was hoping for six months) with a slightly higher rate then previously. I took it because I never had any problems with them and they have never had any hidden fees. The only thing that I have found disappointing is that within 4 days of my contract renewal, rates dropped below where I was previously. Especially, because when I originally contacted StarTex about possibly keeping my previous rates for renewal, it couldn't be done and now the rates are lower. I may consider switching companies in the future if it means lower rates and a better monthly contract. ”

No problems, medium price levels

“  Not the least expensive but have never had a problem in terms of unexpected billing or other issues. Essentially, they are a trade off of paying a bit more for the energy with less hassle - depends on what you prioritize ”

Happy Happy Startex Customer

“  No surprises with StarTex. Have been with them for over 3 years and love the easy to read statements and no surprise billing. I assume customer service is just as pleasant but haven't had to call. Will be renewing with them again. ”

No issues, Good Service

(4 / 5)

“  All customers should pay attention to their contract. Like others, we forgot when ours ran out and our rate sky rocketed. This was our fault, though, but they fixed it and applied the new rate while also reimbursing the high rate. All you have to do is talk to someone like a person, not your enemy. I cannot give them a bad review. ”
