I suggest you report each and every game you experience this via their 'Contact Us' section. As you've said, they do nothing and have no plans to, but a company like this won't change until the cost of fixing the problem is less than the cost of carrying on their crap service. If everyone starts a case after each and every match this happens, their support staff costs will be higher than upgrading their crap servers, paying one geek to fix their matchmaking, and actually dealing with complaints and issues.

Enough user outrage and they will back down as Battlefront 2 showed.
