Query: Could not return this item - JBL CS480BG Speaker System

I've purchased this speaker system however it didn't fit for me. So I've tried to return but amazon said this item could not be returned. I was shocked amazon's return policy and I have to keep this item even I don't need. I've paid $434.72 which is I just lost. If you not really sure to keep this speaker, then you shouldn't purchase it.
