求翻译：我最近在你们商店买了一架数码摄像机，但是等我回到家以后，我发现这架摄像机表面有划痕。而且，当我在室内拍摄照片的时候，色彩很不自然。最糟糕的是我的发票丢失了。是什么意思？

I recently bought a digital camera in your shop, but after I got home, I found the camera scratches the surface. Also, when I was shooting photos indoors, the color is not natural. Worst of all my invoices were lost.
