Florida Power & Light [FPL] review: overcharging from bank account

I have reason to believe that I am being double-charged because I have two accounts in my name and they are adding late fees on both accounts.For example:If I owe 197.07$ and I am late paying that, with the late fee it comes up to 203.73$.They are taking out both amounts and doing the same on both accounts.Account numbers([protected]-08753)
