“ I feel that the staff offer great customer service. They are always friendly and available to answer questions. ”
“ On my latest search for the best energy price available Constellation was the best deal. Easy sign up experience. ”
“
Customer service called and offered a reasonable price for electric, only to find out later we can not use Constellations, if we do not use National Grid.
We are allowed to choose our electric company, but not our gas supplier ”
“ Is good ”
“ One of the best (cheapest) price per therm around. Admin fee is reasonable ”
“ Wonderful ”
“ This has been a positive experience. ”
“ Order was easy. Account transfer no problem. First bill was higher than EFL facts said it was going to be. The distribution charge from the electric distributor was about $10 higher than what EFL said. Called Constellation and asked why, they said distribution charges had gone. They went up the first month after I switched. False advertising by Constellation. ”
“ I have been pleased with the telling me how much electricity I am using and my bill ”
“ eversource did not facilitate the transfer well. constellaion customer service worked to resolve this. ”
“ Had some billing issues early on, but not exactly providers fault. All in all everything was great, however as always good things don't last. Provider probably won't make my current plan available on renewal as it was more likely promotional to attract business, so will have to look for affordable options elsewhere to keep costs in check ”
“ There should be an online method to renew policy... Either I was not patient or the rep talked slowly, either way when I'm at work taking the time out for all the repeated question was a bit weary. When someone satisfied with the services, the option to renew is given. ”
“ No Complaints as of yet. ”
“ Was cheapest service I had in the past years...did not have any problems. ”
“ Good customer service ”
“ so far so good ”
“ I was able to sign up and get the best rate with Constellation and the date I wanted. ”
“ The swap over to Constellation was easy and on time. I wish they had more online tools to monitor energy usage real time or at least close. ”
“ Been with Constellation over a month. Service and billing just starting. Pleased with speed of transfer from previous supplier. ”
“ Having just moved to Waco,TX from Pennsylvania, we had nothing to use a a baseline to compare electricity providers. We picked Constellation based solely on reviews. After 7 weeks, so far so good. A better assessment and review will need t owait until we've been here a full year. ”
