StarTex Turns off Online Account Management

(3.8 / 5)

“  StarTex has a strange policy of turning off the online account management if you do not pay your bill in time. It seems to me that during these times, the online account management tool should be more helpful. Turning it off when you are needing to pay your bill seems contrary to good logic. ”

Consistent, as long as nothing changes

(3.7 / 5)

“  I've been with them for almost 5 years. I made a mid-plan switch in May/Jun '09, when rates sank and I was tied into their 3 yr (roughly $.14/kWh rate) and got into another 3 year for (then) $.119/kWh. I had a bit of back and forth with them after the switch as their billing department didn't get the word that i was in a new plan. After 2 months, they got it straight. The only thing was I allowed them to continue billing the CC as I didn't want to discontinue and draw their ire. Shortly after I noticed that they never updated my new 3 yr plan 'end' date. After I called, they told me it was May/Jun of 2012. You can bet your last buck that I'll be on top of the change so that I'm not thrown into the non-plan summer rate. For others to note (but check, i'm not sure if it's law or the company's position) - but they told me I could submit my 'switch' request 15 days before the last period started). Be sure to check, don't take my word on this.

Overall-I'd definitely refer them! ”

Vanishing competition.

(3.6 / 5)

“  I've been with consolation energy for years now. At first they were better priced than PSE&G, then they became even floating around the same price. Now in January 2024 price to compare, I paid $140 if I were with PSE&g it would have been $70 for natural gas. ”

Unable to reach a Customer Service Rep for Days & Many wasted Hours!!

(3.6 / 5)

“  How in the world do you reach a live person regardless of the option chosen? I have spent many hours in the queue on multiple occasions for hours, then the call drops OR the Representatives purposely disconnect my calls. I must speak to someone since my request cannot be made on line! Go figure. Yes, due to the high call volume, we cannot accept you call. Well, hire more employees for God's sake! ”

in different

(3.6 / 5)

“  Easy to sign up on line have not had any human interaction as of this time. Only been a customer for about one month - seemed like it took a while to become a customer after signing up. A much better rate than my previous gas supplier. Time will tell - invite me several months from now to do another review. ”

Finally got confirmation of service start date

(3.6 / 5)

“  Confirmation that our service request had been accepted with rather sketchy about the start date. I was prompted to contact Constellation to find out exactly when after receiving notice from my previous provider that we had renewed our service with them. Turned out that notice was in error and we were indeed being served by Constellation as requested. ”

Not completely as it seemed

(3.6 / 5)

“  We signed up with Constellation from Reliant due to the rate being lower. However, their fee to Centerpoint is higher which is really never spelled out. It's very difficult in comparing all of the providers since they all use a different format to explain their plans. Our first month my bill was higher than last year with Reliant. Hopefully we'll see an improvement during the hot summer months. ”
