Query: Disappointed and then delighted

Have used Amazon manny times and been delighted. Ordered this dvd not realising that different regions in the world have different 'settings' for playback on dvds and once received I was unable to play this dvd at all.... BUT - returned item and system worked brilliantly. I received total refund inc cost to return item. Bottom line is that I have total confidence in Amazon and would use them for any purchase without any reservation. Thank you Amazon.
