Those sample shots are OOF (out-of-focus). You now need to troubleshoot the problem. 1. The best way is to have someone else try the camera and lens. 2. Next try the lens on a different cmaera body. 3. Now a different lens on your camera body.
Lacking the resources to do this, you may have a local camera store or even a Best Buy or other camera outlet that will let you try.
Something will rear it's ugly head as to where the problem lies but these are easy ways to eliminate each item.
