Can I open a support ticket?

Hi,

I'm experiencing some problem with the depolyment of my new Office 2013 applications within my Office365 Small Business Premium subscription.

I would like to knof if, the above license, I can open support incidents / tickets as I was used to do with BPOS and Office365 version 14 (that means SharePoint 2010).

Is this forum the only hope to get product support for my problems? Is there the way to open tickes as Office 2013 customer?

Thank you.
