Where's my silicone glue/ sticker?

I love it that its magnetic but the bottom is lifting. I watched the video before I bought and I've received the item without the sticker. Does it come with this particular item that I'd purchased? Update: It's been 2 weeks already and I haven't heard from this company. I'm kind of disappointed. The money I spent of this is eh. Now that I've had it for 2 weeks, it does make the screen darker and I always find myself turning up the brightness on my screen. And I also dropped 4 stars down to 2 since customer service is poor.
