Let me start off by informing you how manipulative this company is. They made promises regarding pricing, encouraging me to switch over. However, they’re overcharging each and every month. I even tested it out when I didn’t stay at my home for a month on vacation, and the pricing was still the same and sky rocket on certain days. They literally make their own pricing and just charge you. This is the absolute most expensive, worst customer service, and horrible all around light company I’ve ever experienced. I cannot wait until my lease is up to cancel this ridiculous company. My lease is almost up and I’ll never use them ever again and encourage others to follow suit as well. There’s not one positive thing I can say about this company.

After discovering that the city I live in opted me (without my knowledge) into a contract with this entity I contacted Ameren to inquire about my options. Soon I discovered that the rates I was paying were twice Ameren's rates and so immediately terminated my relationship with Constellation and purchased service directly through Ameren. The following month after ending my service with Constellation (which I didn't even know existed until this moment) they sent me a bill in excess of $700 which I had no choice but to defer to payments. Unbeknownst to me I purchased power at double the rates for at least a year and I struggled to pay these. Once I discovered why and opted out they hit me with the largest power bill I've ever seen. I live in an 800 sq ft home with 1 bedroom, no washer or dryer, and no dishwasher, with my partner and our 3 year old permantly disabled daughter.

We are preparing to face disconnection and homelessness because an entity like this exists. I don't need a utility middleman charging my family double rates without our knowledge and then penalizing us when we discover their and the city's schemes. I need a safe home with affordable water and power to raise my disabled daughter who requires these services just to survive literally. They destroyed me and my family for what?

    About 10 years ago we had 2 heat pump systems replaced by then BGE. They did a great job. We took out a service contract that we cancelled in 2019 that we cancelled in 2020. We recently scheduled a service appointment with now Constellation Homes. I took off work on this day but they never showed. I called to inquire. I was told that they will NOT be coming out as I was in 'collections'. Every time I tried to contact their billing department, I was "disconnected" or could not get anyone to respond. It took a complaint to the BBB to get them to contact us. Turns out that there were NO collections and they were trying to recoup money from my cancelled contract. They now offered to come out but I declined. They are dishonest in their billing, lack any customer service and they cost me an entire day of lost wages. And my heat pumps still have not been serviced.

    Upon researching costs of a home warranty, my estimate turned into a whole house warranty contract. I received a notice that they do not service my zip. I was getting statements that I thought was junk mail. To my surprise I’ve been billed. When I got to speak to a human in charge I was told I could not cancel and that I approved a contract. Trying to figure out my options. I guess next step is attorney general.

    This company is poor with their communication as well as their products and services. They showed up at my house and turned my gas off with no warning, for whatever reason when I called to have them turn it back on I was giving a lot of run around. I simply explained to them that I have a young child at home and if someone can come out sooner that would be greatly appreciated. The representative told me that I would have to get a letter stating my child’s medical condition and then they would have to reach out to the gas company to see if they can send someone out sooner that July 3rd. I then asked for the number for the gas company which she basically said there’s no point of calling them because they would direct me back to my provider. I am so frustrated because no hot water is a huge concern/inconvenience, especially with a young child. I will definitely not keep their services after this.

    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.
