SCAM! Will offer flat rates 24hrs but do not mention added costs and fees that will drive your bill up.
A major red flag should be how the customer service is so concerned about the protocol of the sales reps. They know they are using still tactics that I'm almost sure caused them to be fined in the past.

I was stupid enough to sign with them and immediately regretted it.
To try to make a long story short:

Get out of the contract as soon as you can. Do not let the ten days go by as they say they need that time to process everything when really all it accomplishes is passing the time frame for you to back out of the contract (as per the Consumer Protection Act).
After reading so many reviews and comments about how people had a hard time cancelling this is what I did and got a cancellation confirmation within 12 hours:

I wrote a letter referencing my right to cancel within the ten day 'cooling off' period to be effective immediately and sent it via registered mail. I also told them that this letter would be emailed and faxed.
I faxed the same letter to the fax number on the Summit energy contract and saved and scanned the fax receipt confirmation.
I then emailed the letter and CC'd the following:

Ontario Energy Board, The Toronto Star & Sun, Premier Kathleen Wynne, Hydro One, and the BBB.

Like I said, within 12 hours they confirmed the cancellation.
I sent all documents to the Ontario Energy Board and the lady I spoke to start a file for me and added everything. I also sent everything to Hydro One to confirm that they should now, moving forward, not allowed Summit Energy to make any changes to my account on my behalf.

I hope this helps!

Good luck!
