The Worst Energy Company In The World

(1 / 5)

  This company called constellation would disconnect your power just to charge to several late fees. It takes 24 hr or longer for someone to get back to you.

Constellation Uncooperative Customer Service

(1 / 5)

  I have used various utility services to purchase energy supplies for many years and have never encountered a company to automatically renew my subscription to their program after my program period has expired. However Constellation does. After my 3 years was up with Constellation I found another service at a much lower cost so I set up a subscription with a new company. To my surprise I received a notice that since I chose another service Constellation sent me a notice that they were charging me a $25 fee because I enrolled with another company after my 3 years were up. I contracted Constellation's Customer Service department and they refused to drop that fee. Please be VERY cautious when considering Constellation! I will never deal with them again!

Beware

(1 / 5)

  I have been trying to cancel service since July 26. I set up a move out they shut off early. Got it back on now refuse to turn off. They are rude. I get the run around and broken promises. The minute I mention puc they hang up and say they will leave it on. They have refused to disconnect and I do not live there. Now I switched my new hone and ready to fight paying that bill for old address or the eft fee.

Promise Water Heater Protection and when needed they said, "We made a mistake." We don't service your area."

(1 / 5)

  Signing up with Constellation was a 'no-brainer'. Was the best rate AND a water heater protection plan! I was delighted...however, delight turned into disgust about three weeks into the contact/service period as I had a need for someone to look at water heater. Called for their service as was promised in their contract:
As a protection plan customer, there are n deductibles or co-pays and you'll pay $0 for covered parts and labor up to $2000 per contract year. Plus, you'll receive unlimited service calls and priority service scheduling from our network of local, licensed technicians." I believed this contact as it was signed by Kevin Klages, Senior Vice President however, when I called the main customer service said I was out of their service area. I took issue with this and was directed to the number to call for service on covered equipment and was told the same thing that they made a mistake and don't service the area. They need to "own" their mistake can cover the costs of the service call and repair of what was their 'covered equipment'. I called to share my displeasure with their outcome once my water heater was repaired. I asked for compensation to cover the costs. I was promised on Thursday, 7/1 by customer service that a supervisor would call me back. It is Wednesday, 7/7, nearly a week later and no one has called or attempted to call me from Constellation. I called again the morning of 7/7 to again voice my displeasure at the 'no customer service' in resolving this issue and I spoke with supervisor Ms. Verity, who referred me to another department that handles service on covered equipment - the service they say I don't have. LOL

Constellation are ripoffs, charlatans.

(1 / 5)

  Constellation has a history of ripping people off at the end of contract. They raise your rates and are no longer competitive. Then when you switch marketers, and arrange to change to another, even if you arrange the switch on the contract end date, they try to rip you off with an early termination fee.

How Irritating Can You Get?

(1 / 5)

  From the moment I signed on with Constellation, I was barraged with constant emails, phone calls, and snail mail to get me to do install their junk stuff, promote them to my friends and relatives, and just being a general nuance. I told one of their staff that if they don't leave me alone, I going to cancel with them choose someone else even if it means higher rates. That finally stopped the ongoing irritations.

I enrolled but they never bothered to tell me that AGL didn't switch me

(1 / 5)

  I signed up for constellation on January 10 and received confirmation. Atlanta Gas Light did not switch me to Constellation because I was entered as a new user. Constellation did not bother to notify me of this and I did not find out until I received a $300 bill from Georgia Natural Gas ®. Constellation tried to tell me that they emailed and called me but there was nothing from Constellation in my inbox or spam folder. They did not even offer any kind of assistance with the GNG bill

Liars

(1 / 5)

  I was not happy with my electric company, because my bills were running around $300+ a month. I spent $4,000 getting my A/C unit updated, which was supposed to save me on my electric bill. A salesman came to the door pushing Constellation and showed me numbers that guaranteed that they could cut my bill by at least $100/month. It was mumbo jumbo about how they figured the bill differently in the way that Texas New Mexico Power got its cut. I thought I would give them a try. Worst decision I ever made. The first bill was cheaper than my old plan. After that, it went up and up. My bill now for JANUARY is $387. That is the highest bill ever for my one-story, 3 bedroom house. I was going to cancel, and they informed me I had a 2-year contract. That's not correct, as I would never sign up for that long with a company I am trying out. Somehow, they slipped that in without my permission. What a rip-off. I will never use this company again. Don't believe whatever they tell you.

Fraudulent Charges, Scam-like Business

(1 / 5)

  Constellation is the WORST electricity provider!I was a loyal customer of theirs for eleven (11) years!When I transferred their service from one address to another, they locked me out of my existing account, making it impossible for me to pay any bills from my old address.They charged me my ENTIRE electricity bill for four days of service (the overlap period between addresses). Now they have a Collections Agency bugging me to pay their FRAUDULENT charges. And folks like you and I are powerless to stop these greedy corporations from acting like highway bandits!They have apparently sold the debt (for pennies on the dollar I'm sure) to the notorious collection agency, McCarthy Burgess & Wolff.These folks are beyond unscrupulous and the fact that Constellation does business with them tells me all I need to know about them.
