Pilling after 2 weeks

I have another slipcover in the Stretch Plush and absolutely love it. But I needed a Navy blue and since that doesn't come in blue, I chose the Stretch Pique. Even though I lint brush it and hand vacuum it daily, the little raised diamond shapes are pilling, which in turn has attracted a lot of lint. It just sticks to it now and I can't remove it. Unfortunately the cover looks kind of trashy now. We don't have small children or any pets, so I'm not happy at how quickly it is deteriorating. I might call SureFit to see if they can suggest something as far as cleaning. At first it made my duck fabric sleeper sofa look like new, but not now. I wouldn't recommend it in the Navy.
