I recently spent an hour changing to their 3 year electric rate of 17.49 cents, and everything was completed, including 3rd party phone call confirmation. Next month I found they were still charging me 38 cents instead of 17.49, I called them and was told the process was not completed. I was paying higher rate for 2 years, because they failed to do the change 2 years ago, and then I never checked my bills. This company without doubt is very dishonest and robbing customers. Please beware. I will talk to Attorney General's office if they can take class action lawsuit against this company.

My heat was turned off with a $0 balance and then to make matters worse, I had to wait 5 days for a technician to come and turn it back on. Customer service told me that it was not an EMERGENCY unless I have a gas leak. Are you kidding me, this was your fault!!!! I would not recommend this barbaric company to my worst enemy. DO NOT LET this company service your heat.

    I received a promo rate years ago for my electric that was better than Potomac Edison. My bill was never higher than $350 in winter. When I started getting bills over $400 and then $500, I contacted them. They jacked my rate up to 14kWh- far more than Potomac Edison's variable 6-9 kWh. I have been overpaying for months because they don’t put their rate in the bill and calling takes up to 5 days for a response. I feel extremely cheated by this company and want everyone to beware of them.

    Subscribed to their service in 2013. Must have been a good deal at the time. Checked my price recently and they were $500.00 higher monthly than the local company. I do not know how long this was going on, they never made contact with me once my initial contract us up. I was then billed a "variable" rate. This most likely has cost me thousands over the years. It has taken me 4 days just to reach the company to get information. Hold times were anywhere from 2 to 4 hours for commercial customers. I was able to call and reach Customer Service for residential customers with limited hold times (6 or so minutes). I was always transferred, ending in several hours of wait time.

    In order to go with our local gas company, I had to get a disconnect from this company before my local gas company could switch my services over. I had no choice to to endure the wait times and it took close to 5 hours on hold before finally getting to the correct Customer Service Representative to complete the transfer of gas services. Horrible customer service I would never recommend to use this company. Don't make the mistake I did. If you don't hear from them, get in touch as soon as possible. Good luck. I'm happy to finally be done with it all.

    Due to an automatic payment glitch, my gas was turned off for 5 days. We have kids and the weather will be in the 30’s before we can get it turned on. The customer service was terrible trying to work out this issue. We will definitely not be using this terrible company again. We would have appreciated a phone call or text before turning off such an important utility. We were told that kind of service was way above and beyond what the company was comfortable paying for. Constellation, after 12 years as a perfect paying customer, I will definitely change to a company that values its customer’s needs and safety.

    We recently purchased a new home and tried to switch Constellation over. When we renewed our 3 year contract, the sales guy told us that service is transferable if we move and we are guaranteed at the locked in price. After being on the phone for countless hrs, they insist on transferring service to the new home at a higher price than what we are in a contract for. So what is the point of a contract??? After being transferred to many reps, our call was finally escalated to the mgr. We received a call back from the mgr himself and he said we can transfer the service but at a higher rate. We told him that this was not what we were told and was very dissatisfied with this service and will be writing a review. He hung up on us! TRUE SCAMMER action! Please do yourself a service and use some other company and not Constellation. It was a horrible experience from the get go, from setting up the account for auto pay to billing.

    I received a PowerPlug from Constellation for being a customer. It works with an app that allows you to remotely control whatever devices (appliances, lights etc…) that you have connected to the PowerPlug. It was a neat little gift until it wasn’t. I’ve been unable to get on their app because it won’t recognize my name. After countless phones over several months they still can’t get it figured out! When I call now it’s the same old, "We’re working on it, will call you back" etc… A large amount of wasted time with no results. Now they don’t return calls or offer any assistance except to apologize profusely when I inquire to what the status of my work order is. So I have a plug that is essentially just that a plug. I’m so frustrated with their incompetence and indifference I don’t see keeping Constellation Energy when it comes time to renew.

    We have used this company for several years and have been pleased with their service. Plus their rates have been fair. During peak times, adjustments in relation to usage have been appropriate. They have been very responsive during any power outage or other issues that have arise.

    I finished a three-year contract with Constellation energy. And switch to another energy provider. Unbeknownst to me constellation seemingly sent me a renewal notice that I did not get. As a result of my switching to another company they hit me with $150 cancellation fee for the contract that renewed itself without my review. Calling constellation resulted in a unsatisfying call that indicated The only way to get rid of the $150 charge was to renew my contract with constellation. This should not be permitted. Contracts should be required to be reviewed by the buyer at renewal and I believe that constellation energy is violating some sort of consumer protection for the state of Maryland.

    If you use this company and want to pay automatically by credit card, be prepared for a disaster. The web interface is horrible and the customer service function is partly outsourced, and doesn't work well at all. Use Constellation only if you want to waste time on hold and deal with constant billing problems. This is easy with all of my other utilities and they have made an absolute mess of it.
