If I Delete Downloadable Content on My Wii Console, Can I Get My Points Back?

My friend brought his Guitar Hero game over to my house, and I bought some songs on it. If I delete the save data for it, do I get my Wii points back? Can I re-download the songs for free?

Suggestion:

No sorry, because if you did, then everyone would be able to buy games and downloadable content and after they are finish, they can refund it, NO, that's the reason. sorry kinda mean there
