My son, girlfreind and others are currently in puerto rico they travelled out on Mon 13th for 2 weeks staying at polemar apt. One of them attempted to buy a camera from an ellectric shop handed over 35euro then the sales guy said the camera was not in stock. He then asked for his money back and the assistant said "no camera, no reciept, no money back" and then told them to leave the shop. My son and his mates are only young and are left not knowing what to do. If ther is anyone out there who could help please do so. This is a big lesson to all.
