Energy Provider Selection
Selecting a provider was virtually seamless for Electricity. You choose your plan, go through entering the info, submit, and wait to hear back. You get a confirmation from both Constellation and your supplier to confirm your selection. |

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. |

Customer No Service!
Constellation sent letter thanking me for my request for level billing.
I did not order that. Tried calling their customer service number for the last 3 weeks at various times during the day. You remain on hold listening to messages about how important your call is to them. After several calls remaining on hold for 35 mins. I was cut off. Exactly the same cut off time waiting on 7 calls to them. Ive sent requests for change back to actual usage billing online 3 times in the last 2 months. Recording says you can send email. Tried that, no response. Promised gift card after first 3 months of service for signing up for their electric service. Still waiting. They were the lowest cost electricity provider. Once you sign up they are gone. Promotional gift cards are promises with no delivery, |

Issues being an AEP Ohio Customer
It is time for me to sign up for a new electric supplier. I found a great rate at Constellation for 36 months. I tried to sign up on line, and kept getting an error code. I called in and spoke to a rep, who told me that since my SDI started with "000" I was not an AEP Ohio customer, I was actually with AEP Columbus Southern Power, which changed my rate from .549 to .579...pennies, I know however I was concerned that there would be issues with my bill because I knew I was, in fact an AEP Ohio customer (have been for 13 years...in the same residence). So I called AEP to verify with my name, address, account number, etc that I was indeed an AEP Ohio customer, and she says "Yes, you are definitely our customer". So I called Constellation again, trying to let them know I got verification that I was an AEP Ohio customer. Due to an error in their system, they cannot process me that way, they "have to process me as AEP Columbus Southern Power". I told the supervisor, George, that there must be an error in their system, and that I could not go forward with setting up my account because I was lacking faith in their system. I returned to the PUCO website and went to the next lowest price, which was .579 with Direct Energy, entered the same information that I gave Constellation (name, address, SDI, AEP Ohio) and the order was processed in less than a minute. Frustrating to know I wasted so much time today TRYING to give someone my business...but I wanted to put it in writing that you all need to check your system...it's wrong! |

Constellation
Took too long for the supplier to change over to Constellation and then from Constellation to my next supplier. However, this may be a problem with our Electric Company. At the end of my contract, my electric jumped really high with Constellation so I switched again to a different company. |

They cancelled ME!
I was happy to sign up with Constellation for electricity. A rep called to welcome me to Constellation about a month ago. Then this week I got a letter saying I was cancelled. No reason. So it was back to Apples to Apples to find another supplier. |

Too early to review
It has been 2 months since I signed up with Constellation as my natural gas provider. The actual switch did not occur until 27 July and I have yet seen an invoice from Center Point with Constellation on the invoice. Meanwhile, Constellation has enrolled me in their reward point program as invoices catch up. |

They disregard rejection
My daughter expressed interest in changing the constellation but the electric is in my name so she gave them my email address and after being prompted many times to complete registration and not doing so, they went ahead and subscribed me. Their prices are so much higher than others available I would never have chosen them but they moved forward without my consent. |

Terrible
So, I signed up in April, then come June I get a letter that they had my account number wrong, which I don't know how I could mess that up if I am looking at my bill when I enter it.... but anyways. I call to fix the issue, now after the rates went up I have to sign up for their services again at the current rate. Such a rip..... I signed up for a 5.9 rate in April, signed the contract. Then get this BS and have to sign up for the new rate of .94.... Tell me that doesn't sound fishy. |

Constellation Uncooperative Customer Service
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! |

How Irritating Can You Get?
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. |
