nektariosf on "[Plugin: Jetpack by WordPress.com] Problem with contact form"

Hello to everyone

I created a webpage with wordpress 4.0 for my school and I used jetpack 3.1.1 for many things but I have a problem with the contact form. I created one here
http://5dim-ermoup.kyk.sch.gr/?page_id=34

but I cannot receive any of my test messages. What can I do to fix this situation?
