The ordeal is over! I received a new case yesterday and there's nothing wrong with it. It's new, it has all the requisite parts. I think what they sent me before was a used/returned item. It had a lot of scratches as if it was dropped, probably causing the bottom part to break off. I imagine that someone decided to take advantage of the system. Their case broke, they bought a new one, took the new one, and then returned their purchase except they placed their old, broken one in the box. At the warehouse they picked up this returned one and sent it to me. I'm probably not too far off on my story.
The upside of this whole thing is that each time they sent me a shipment, they also shipped a package of screen protectors. I bought one originally because it was only $10 when it's normally $20. Well, they wound up sending me three packets. Maybe I should sell one online and keep one as backup.
In any event, my iPhone is now encased, or is that Incased?
