People often make mistakes in real estate transactions and it is not uncommon for charges to be omitted.  I would not make a big deal out of this.  Find out what the charges are where you can asure yourself that you are not getting charged 2 times for the same thing.  Also, find out what the charge is as that is a big number on a settlement statement.  If you fail to pay the charge and it is a lawful charge you could get sued.  If you want to play hardball, you can tell them that you refuse to pay and they will have to sue you for the amount or offer to compromise the fee (i.e. tell them you will pay 2K to resolve this matter).  I would confirm the numbers and then pay the amount as i am sure it was an honest mistake.
