Unhappy about excess fee account no.:***

Greetings

What is this excess charged for on my account.This unfair and *****ulent because they is never an explanation for it and I don't understand why we have to pay it for what. I would like it removed because even last time I was told its an error and how is our small businesses suppose to go forward when we have these surprises. I don't appreciate it.This *****ulent because the excess fee just arises the next morning into account.
