WebForm Submission Contact Creation Not Creating Contacts

WebForm Submission Contact Creation Not Creating Contacts

I have built a webform that submits user information into the cases module.  I have also embedded this form on our website and the form submission is working perfectly.

The Issue:
I have the "Enable Contact Creation" option checked and when a new webform is submitted a corresponding contact is not also being created.  Secondly, if I submit a request via a test user that already exists in the CRM, the cases are not being related to the existing contact. 

URL of the form:   http://www.naturalsplendor.com/contact-us/
