Can the charge port on my son's Zune 30gb be fixed?

I got it for him for Christmas, and the charger started sticking when we tried to remove it. Soon one prong of the charger broke, so we bought him another charger. The problem now is that the port inside the Zune device itself, where you plug the charger in, is now askew (crooked!!), and has rendered the entire Zune useless, because it can't charge. Is there a way to fix this (or have it fixed) without paying more than I paid for the device in the first place??
