I Actually did not hate this, but by accident when I ordered it I did not realize that I already own it and have seen it. I was wondering how on earth to return a product for refund or as credit towards my next purchase. I emailed the site but never received a reply. Could you help me? I was actually in need of season 5, not 4. The wrapping is still on the DVD set, may I return it and if so, how?
