Syncing data issues

My Forza Motorsport 6 isn’t syncing data. I have been waiting for it to do so for a good 3 or so hours and nothing has happened. I’ve contacted Microsoft support and done all the troubleshooting and the likes but nothing has happened. I had the issue with Horizon 2 a while back and sold the game as I couldn’t get it to work. Would like to know if there’s any way to resolve this issue for good.
