We are not responsible for Zonbu's actions, please mail their customer support for clarification I suspect they made a mistake. If you experience problems with Banshee then using our bug tracker is a good (but admittedly a slightly complicated) option
http://bugzilla.gnome.org or the zonbu one
http://bugzilla.zonbu.com
We are however not affliated with Zonbu in anyway other than the fact that they use Banshee in their product, support requests should be made to their customer service.
I do however happen to own a Zonbu box myself, and if you would be able to explain what your problem is, I will be happy to spend my spare time looking into your problem out of the goodness of my heart.
