Very uneven

Of course, signing up was easy and seamless! But when it came time to re-up, 1. I had too many numbers to call which one?
2. So much ro-bo interface, to just repeat the same things to the human. So much time on hold.
3. The human in the first call was a knucklehead and could not answer my questions AT ALL. Then he started saying (whining) things like, you dont understand. Oh, yes I do. Goodbye.
4. After trying a few more numbers and being quoted wildly different prices, I found a human that knew what she was talking about, who quoted me a reasonable price, and the deal was done.
Not quite the same experience as the initial sign-up!

Disappointed

On 12/8/2018 I called Constellation to apply for service. I talked to Mario and gave him all the information that I had at that time but I did not have my electric ID number, only the gas number. Mario gave me the number to call him back when I had all the information, he also gave me (what he said was his personal number with the ext. number 616). I called back within 10 minutes. When I call back I gave the person who answered the phone the ext. number that Mario had given me, I could tell by her tone that she had no clue about an ext. number. When I asked for Mario, she said that he was busy but she would help me. I explained that I had given Mario most of the needed information and that I would like to continue talking to him. I then asked her if she would ask him to call me back. I was told the they do not return calls, that I would have to call Mario back. I called back 4 more times and was told that Mario was busy each time. I was dissapointed, first because I have never heard of a company that does not return phone calls and second because I feel that Mario was blowing me off, also the rates that he had given me were lower than the ones that I saw on line. My guess is that he made a mistake on the quotes and did not want to admit that he made a mistake which was not a problem because the rates on line were the lowest and I would have been happy to complete the application. As a result, I continue to look for a company to provide my gas and electric service.

My Order Never Went Through

I received a confirmation number for Constellation Energy. I thought everything was complete, never received any follow up. I received my most recent electric bill and it was astronomical. Turns out, the order never went through and North American Power jacked my rate up to .16 per kw/h. First, this website is terrible. Second, North American Power is getting away with highway robbery. I am on the hook for $250 extra this past month, and again this month until the new plan kicks in. Remember when they said deregulation was going to be so great for the consumer? It's only great for the energy companies.
