Minimum Usage Fee increase

(3.2 / 5)

“  I was a customer before they were bought by Constellation Energy. I called them shortly afterwards and told them I would give them a chance. One of the deciding factors in choosing them in the first place was the minimum usage fee. I use below 500 kWh one month a year (maybe) and in the past 12 months I have used below 1000 kWh 9 months. With the new minimum usage fee increase and not offering anything below a 12 month plan. I will be paying an extra $90 a year. I have decided to fire StarTex and switched providers. They were charging $4.99 as a minimum usage fee below 500 kWh. Now they are charging $9.95 for a minimum usage fee below 999 kWh. I did call customer service to see if there was anything they could do, since I had been a customer for over 3 years. I was told they have had meetings and was nothing they could do about waiving this fee or modifying it. ”

Disconnected my service without notice

(3 / 5)

“  Constellation Energy disconnected my service without properly notifying me. When you call Customer Service, they will verify that they have the right phone number for you three times, but no one will take 1 minute to actually use it to call you, even if you owe them money. It just happens. No letter, no email, no phone call. Nothing. It's easier for them to just let your service get disconnected. Then, of course, you'll contact them to pay your bill. It's easier for them that way. They don't have to lift a finger. Very poor treatment. ”

"Authorized Representative" Option

(3 / 5)

“  I enroll our home, also two other accounts (older ladies, one is 93 and the other is 100) - in the application process, there is a place to include an "Authorized Representative" and I properly entered my name as an authorized representative - however, when calling customer service, I am NOT included as an authorized user on any of them - not possible to put the older ladies on the phone to authorize - including such toption is a good idea, but disregarding the "authorized user" is unforgiveable ”

fine at first

“  we were very happy with the price. very affordable and good service. but then it came time for renewal and I missed my time. the price jumped and now I have a ridiculous bill that I cant pay. I have been very unsuccessful at changing the plan to a lower rate. the website is useless for choosing a new plan. ”

Just starting w/ Constellation

(3 / 5)

“  Since our present electric company's rates have jumped dramatically we decided to try another company. I can not
share Constellation's business procedures; we Just became Consellation consumers - however, I will say that the information that was available for us to 'compare' their company w/ the others was extremely helpful. The procedure was a snap to sign on. I only hope that the rest of our contracted time will be as 'comfortable'. ”

Lack of Communication

(3 / 5)

“  I changed from Scana to Constellation because they were recommended to me. After ordering the change online on their website, I was continuing to receive bills from Scana. Constellation did not communicate with me to let me know what the status of my account was, or whether they had cancelled Scana's service. Three months later, I called them before I paid my Scana bill, and they confirmed it was being processed. That seems like a long time to "process" and order, and with no communication, a bit concerning. I now have received my final bill from Scana and my first bill from Constellation. I hope their service is better than their lack of communication. ”
