Xbox 360 - First match of the day OK, then cycles through the 10 server connection attempts

it's been 12 days since I bought this game and since day one I've had this same issue. I opened ALL recommended ports and even tried that belkin thing where they ask you to change the dns on your xbox to primary 4.2.2.2 secondary 8.8.8.8. No luck. I contacted EA twice and the first guy told me they already knew about the problem and it would be fixed within a few hours. The second lady was a lot nicer and actually tried some troubleshooting but in the end she too gave up and told me this was a known issue and there was nothing she could do. I took my disk to my friends house to see if it'll work there. Whatda know the game worked perfectly on his xbox. Not even lag and he didn't even have to open any ports. I have no idea what the difference is between here and there, maybe the difference in routers or the fact that he has the halo 4 edition xbox 360 and I only have the slim, or he uses DSL and I use Comast. Whatever the difference is I can't play on my xbox and he can. This error should be resolved already. It's obviously something miscommunicating between the game titanfall and the xbox 360 console itself. No **bleep** about how it must be our crappy connection or make us feel bad like it's something we did wrong but this is clearly how the game was designed to interact with out consoles. If you're going to release a game that doesn't work for everyone on the platforms you release it on, don't shrug your shoulders and say "oh well sucks to be you" and then try to sweep it under the rug. Help us, do everything you can to fix it or offer a refund because as of today, nearly 2 weeks later, my game it still unplayable.
