Citi Mortgage UX Fail

CitiMortgage Payment Dates Recently I was on the CitiMortgage website (www.citimortgage.com) and noticed a poor design decision in the date selector. The company policy prevents you from picking a date past the 16th of the month. The drop down list to select a date, however, presents the user with all date of the current month but will show an error message if the user selects any date past the 16th. Why even present the user with those options?
