Best price overall

The price for the electricity most months was less than all of the service charges and destination charges from the illuminating company. That saved us a lot of money in every season

Friendly, helpful people.

When I had questions and when I told them I was considering changing my plan, everyone was still super nice and friendly.

Switching to Constellation from Energy Harbor

Constellation had the best price over all others for a 3 year fixed plan. The sign-up process was very easy and I am happy to be one of their customers for my electric service.

In different

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.

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.

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.

Never got to use them. Bandits

Tomorrow Energy is still on my Duke bill and they are changing the rate every month: Low was 0.059 and high was 0.140.Trying to find out why. Who regulates this PCU and how do I get rid of these thieves. We are retired and on a fixed budget and this hurts.

Wanted to go back to our orginal provider

We did not realize our city we live in went into a contract with this company and how we found out was getting our first bill which was way higher then we had been paying before. I have made more phone calls then i care to say and even have an email from rosa a supervisor telling me i had been removed from the program and back too my orginal electric company. Got another bill with even more charges from them and literally called customer service again to have an agent laugh i dont think its funny in any way. This issue was suppose to have been resolved already but of course its not. Horrible customer service... Im following the steps and my next step is the bbb on this company. You better stick with aep guys this company here is a joke!

Door to Door employee RUDE and Obnoxious

Just within the past hour, I had a young man, literally beating on my door. Upon answering, he introduced himself. I immediately told him that I was not interested. (my time is precious, as I am sure his is too) He proceed to explain that he was not selling anything. Again, I told him and very politely that I was not interested, at all. He then insisted on arguing with me, why I should listen. NOW, my patience is growing thin. I asked him to leave. He stated that I was rude.
NOW, He's a stranger that showed up on my doorstep. I did NOT call and ask him to come to my house. I did not ask him to BEAT upon my front door. Short, He was not WELCOME. I had asked him to leave several times which he refused to do. All he wantred to do was argue.
I suggest that YOU Better, Train and educate your employees. They're behaviour is a direct reflection of CONSTELLATION ENERGY. He didn't leave until I closed the door.
