Query: Where 's the rest!

I ordered and returned this item twice. I returned it because the extra materials were missing. The second time I asked for a refund. It wasn't Amazons fault that the materials were not in the DVD since I recently found that few if any had the materials in them since the producer forgot to include them. Amazon however never mentioned that to me. Shame on them.
