Cod black ops 3 dlc download problem?

okay i put the download of annihilation for Xbox360 so It reaches 99 percent and It doesn't download anymore. WTF i mean i thought it was my internet connection but i waited like an hour and still same. So i cancel the dl and put a fresh new dl of it again and have waited another several hours. And still the same result. So is this like a world round problem or is this just me. ANSWERS QUICK ty.
