NOT A GREAT TIME WITH CONSTELLATION

(1.6 / 5)

  AFTER 8 DAYS THEY TURNED OFF MY GAS AND SENT ME A BILL. I CALLED AND STATED WHY DID YOU TURN OFF MY GAS. THEY SAID YOU DONT HAVE ACCT. I SAID WELL YOU SENT ME A BILL FOR GAS AND I PAID IT. I HAD NO GAS FOR THREE DAYS AND WENT THROUGH 3 PEOPLE TO GE IT STRAIGHT. THEY HAVE SO FAR SENT ME 3 ACCT NUMBERS. JUST A RANDOM TURN OFF OF GAS??? THEY TOOK RESPONSIBILITY FOR IT AFTER 4 HOURS OF HELL. WHAT IF IT WAS WINTER?? I WAS IN AND OUT OF TOWN AND MISSED WORK AND HAD TO HIRE SOMEONE TO TRY TO MEET THE GAS COMPANY. REALLY NOT A GREAT EXPERIENCE.

Beware their "late fee scam"

(1.5 / 5)

  Give yourself a good 5-7 business days prior to the due date if you bank on-line, since they refuse to set up an electronic relationship with anyone but Wells Fargo. 3 times I've gone through this. If you send your payment through another bank along with your other monthly bills, leave lots of lead time, otherwise you'll get a nice pink greeting from them in the mail along with a late fee charged to their next bill. Then, when you call to see what happened and ensure that your service is still on, they make you feel like you, as the customer, have done something wrong by banking on-line, and not going to one of their preferred payment systems (mail, call their payment number over the phone, or wells fargo). Excuse me for not wanting to jack around with 20 different service providers and desiring to handle and manage my bill payments through my own bank on-line. As soon as my current contract expires, I will be leaving this provider.

Startex bait and switch

(1.5 / 5)

  Got Startex on their low price on the powertochoose site. I didn't read the fine print, and the price went from about 6 kwh to 16 kwh...why even have those bait and switch prices? Just put your price up their and quit trying to screw the people.

Cutomer Service - take a nap while you wait

(1.5 / 5)

  Website account management is problematic. I called customer service last month and had to wait for 22 minutes. I'm on the phone again, its over 28 minutes and no luck yet. Startex Power, where customers see stars. Service charges have doubled.

(1.5 / 5)

  here is Our experience
DEREG's : (not one co. explains the convoluted plans, very very bad for NOOBS)
what that means ,is vast complexity !
we moved Texas July 26,2011
some how the company changed hands , last month.
and we got no bills for July. (we keep reserves for when we travel out of country.
I got no warning that my rate would go from 9 to 13 cents/kw ! ouch (floating bla bla's)
I called and asked why no bill. Lost or USPS?
I owed a tiny extra amount and CC it, now.
and then was told our contract expired.!
ok ,been here 1yr +15 days,. so signed back up.
(but odd how contract ended in june?)(not told)
but at the end of the week , i get a huge bill.
NOT HAPPY, with StarTEX power.
I will switch and pay the $150 if they dont
agree to correct my billing.
No email was sent to warn us.
not resolved.
NOOBS,nail the contract end date to the wall.
or get burnt. In Texas.
Set stat to 79F. (works great in summer)

Web site needs work, a bunch of work

(1.4 / 5)

  I have yet to be able to contact any one to set up direct billing - too many gate keepers, too long on hold, most of the help is very difficult to understand. And the web site is of no help. Have had to pay my bill as a guest. Oh, and I've had two bills so far: one for a partial month of customer service fee one for some bogus "new service fee" that I was not told about. I have yet to pay for any gas usage.

Going back to scana.

(1.4 / 5)

  This company is a joke. Lied about a gift card for signing up. Rates changed sporadically. The customer care doesn't care. So I am going back to scana which I never had a problem with.

Constellation is unorganized

(1.4 / 5)

  I signed up to move my service to Constellation - it never happened. I had several calls, kept giving the rep the same info and my request was never processed. No response from Constellation to let me know what was happening but I just got another bill from the provider that Im trying to leave. so apparently they still havent figured out what theyre doing.

Beware this company sells customers to other providers

(1.4 / 5)

  I was fine with Constellation until the day I received an email stating my service had been sold to a provider that, when I looked them up, had horrible customer ratings. I paid all my bills BEFORE they were due, never bothered them for anything and yet one day I was dumped, period, end of story. As of such and such a day, my service would be provided with another company. I called them up. I had most of a year left on my contract and said I'd rather cancel and pick another company I wanted. Nope, can't do that - we have your contract and we can assign it to another company and there is nothing you can do about it. DO NOT USE THIS COMPANY!!! Not unless you want to find yourself with another company that has a D rating with the BBB without recourse.

Beware (DO NOT SIGN UP WITH CONSTELLATION)

(1.4 / 5)

  Don't get me wrong, they were great for a few years but their latest antics put me over the edge. They doubled my KWH rate which drove my bill up over $1000 per month. When calling them, I sat on hold for an hour and a half only to have them pick up, not say a word and hang up. I am beyond livid. This is a horrible way to do business. I am changing providers as quick as I can.

Unbeleivable

(1.4 / 5)

  I just purchased a new car.
Purchasing the new car was a much simpler process than setting up an account with Constellation Energy .
The woman who helped me set up my account was very courteous and profesional.
The process of Constellation Energy is beyond belief.

OK while you have them, but stink when you decide to leave

(1.4 / 5)

  Had Constellation for a couple of years. When it was time for renewal, a competitor gave me a MUCH better rate. They delayed the switching dates and charged me about triple the therm rate for the extended period I was stuck with them. I called when an unexpected bill came in that showed me as STILL being a customer of theirs, but was given less than zero help.

Where are they?

(1.4 / 5)

  I signed up for Constellation to be my carrier. Several times they attempted to contact me. I called them back. They asked me for the meter number which I read them every number on the meter I could find to no avail. I suppose Ga. Power never submitted it. I have yet to receive a bill. I'm only using gas for stove top at this point which, I'm sure, is minimal amount. Later I plan an on demand water heater and whole house power generator. It would be nice if Constellation would come by, get the meter info and set up my account. I'm not at home frequently but they wouldn't need me there to get the info they need. Meanwhile, I'm receiving free usage which I wish they'd get corrected. Because of the hassle, I believe they should set my account up without a connection fee. Just bill me for the gas I've used since inception. I want fixed rate billing, not variable as I do not care for surprises.
