Day's and i still cannot get online

4 days so far, try to click arena, warzone or custom game and all i get is an error stating unable to access lobby service. Just recently got this game played through legendary campaign solo then was finally ready to play some online and all i have got since is this. Love the game but i have wasted my money no one will reply me about a fix i have emailed everyone associated with it that i can i have called support i have spoke to anyone who is anyone and !!! nothing. No one gives a damn that i cant play at all, i paid for the game, i pay for my xbox sub, i even went and bought new ethernet cables, i tried on three different isps but no still cannot play so thanks 343 or whoever has caused this you have destroyed this game for me.
