Enrollment Failure - No Contact

I tried to enroll in service online (order TX28746724), and I even contacted support to make sure everything went through and I was told yes, everything was good. Now nearly one month later I find that the enrollment did NOT go through and no one can tell me why and now I'm stuck to pay the delivery fees through my apartment complex and penalties for not having service setup, despite being assured from Contellation that I would have service.

This is one messed up company

This is one messed up company. They clear the check and then send you a disconnect notice. On top of that, they hold the checks for a month before depositing them.
Whoever runs their departments are brain dead idiots.

Found the representative very forceful in his sales pitch. Was switching carriers and was on the phone with him for an overly( in my opinion) long conversation. He was trying to upsell me on ac/ furnace warranty even though I had explained to him that my units were literally 5 days old and already guaranteed. I also was taken aback when he asked for my SS# to do a credit check,even tho I had been a previous customer. Had never had that happen with other utility providers. Maybe he thought that he could bully a 75 year old female into extra purchases ,but he has never tangled with an elderly Scottish woman. Sorry ,just my opinion.

Constellation customer for years

Constellation customer for years. No heat for over 20 days. The first technician came out on 12/19. He expressed that he did not work on propane heaters and left. The second technician stated that new burners may be needed. The third technician arrived on 12/29 to install the burners. He made no attempt to test the new burners but stated that the previous technician should have known a new system was needed. We were advised that the expected parts would arrive on January 5. No response from the company. We called and were advised that the parts might be in the boxes delivered to their office, and they would confirm. No response. We called again on January 7 and left message. Received a friendly call back from CS Rep and was advised that only 3 of the 4 parts had been received and that we should expect a call from the Expediting Dept within 24 hours. Twenty-four hours later, - CRICKETS. I called again. Now told the number I'm reaching is for new installs only. CS Rep checked anyway. She tells me the burners are on order. Ugh!!! I explain the above to her. She sends me back to a previous number that sent me to her. Now working with another CSR. All Reps were kind, but No ETA to share. Reached out to BBB. Constellation responded to complaint saying a technician was schedule. BBB closed ticket saying Constellation acted in good faith by responding. Technician came and repeated what technician said on 12/29. Still no heat. So far, 25 days without heat and very poor communication from Constellation. NO ETA in sight! Don't believe the 'A" BBB rating. It's time to move on. Obviously, they don't mind losing $$$ to install new equipment and renew their service plans. We're moving on!!! Goodbye Constellation!!!! UGH!!!
