Please fix bugs

I bought this to aid in tracking my sleep and activity. I was excited about the other features like the messages, phone calls, and calendar sync! Now none of them work. Even after turning Bluetooth on and off from both devices. My sleep no longer syncs to the app either!! My calendar, messages and phone calls no longer show up in my band! All that money and all I can do is count my steps!! Please fix these bugs soon!
