If I can't use product for which it is intended how can I give a good review?

Not able to use this product, because it is no longer available in stores music can not be downloaded. I'm not sure why my review is not being accepted. If I can't use product for which it is intended how can I give a good review?? I am hoping I can return the item because it does not work, what good it purchasing a warranty if it is not fulfilled. Who can I get in touch with on order to solve this problem. Do you only respond to good reviews. I spend a lot of money with Amazon and would hope to be able to return something that does not work.
