Problem with Contact Form

Hello all,
I’m having an issue editing a Contact Form.. Under my Dashboard, I found the section “Contact” with subcategories “Contact Forms” and “Add New”. When I click on the Contact forms, it brings me to the settings.

My issue is found here: http://www.hgrgardensupply.com/about/

My issue is the “quick contact” widget thing on the right side.
I’m trying to edit the description, where it says “Need a quick reply to your questions? Fill the form, we will reply in max 24h”

I want to edit that so it actually makes sense. When I go to the contact forms in the dashboard and look at the settings, I find everything dealing with “Name”, “Email” and “Enter Your Message”.. but I see nothing on editing the description. Maybe I’m completely in the wrong area? Has anyone else had this problem?
Thanks in advance!
