Double Purchases

Quite some years back i purchased Disclosure albums - Seattle, both the deluxe and the extended versions. I tried to re-download them from the store but they aren't there. I check about and still no luck. I am confused, and now i bought another copy of the deluxe album.

Can i get some assistance with this?

Edit: I was able to locate the albums (with many more) they were hidden.

Although i still purchased the album a second time, how do i apply for a refund? Or does it cancel out since i already own a copy?
