Query: bummed out

I love all these movies and bought the entire collection for a Christmas gift. All of them were defective. I sent them back for a replacement and those also were defective. So.. I was very bummed out. I spent too much time printing our return/exchange forms , visiting the post office etc. I ended up just getting credited to my account. I don't want to blame Amazon because this is my only bummed out experience with an order I placed. Maybe it was the dvd company????
