FirstEnergy Solutions Added Cancellation Fee after Customer cancels. Akron Ohio

As many have already stated and complained about FirstEnergy Solutions, I also was sent a cancellation fee notice when I switched to a more reasonable energy supplier.  I went with FirstEnergy when they had good rates, and also there was no term limits, or fee to switch to them, or to cancel out of their contract.  Now when their rates have gone up and many are stepping away from FirstEnergy Solutions, they are self-imposting a $100 cancellation fee.  Trying to call them has turned into a problem.  No where did they have any information on when they "added" this cancellation fee, yet in the process of switching from them, I get a notice of this "self imposed fee."  I have reached out to the better business bureau as well as other agencies, and find out that many are in the same boat.
