Tonight, 56 minutes into a relaxing movie it froze - a defective DVD. I called the phone number (on the box) for the Blockbuster where I rented the film and there was no answer. I waited and called again, it rang and rang, but no answer. I checked the website and confirmed that the phone number was correct, called again, no answer. I checked store hours online and saw that they should be open, so I went to the store. I asked one of the cashiers what to do - she told me to get another copy of the DVD and exchange it. I did so, and went back to her but she refused to acknowledge me. The line in the store was very long, but I only wanted to ask if if she meant for me to leave the DVD that wasn't working and take the replacement, or if there was something more I should do.
