I know you had issues yesterday, but not sure where you are getting 50 bucks from. TW is only as good as the infrastructure at each venue and the local people running it. I've watched and had a feed go down all of a sudden or the sound disappears before. All due to someone killing the feed In the arena or hitting mute and forgetting to unmute. Can be very frustrating. Yesterday, I started watching the Ev. North Regional in the 2nd round and had no problems at all.
As for your situation, you should have been able to get a refund. And if not, I know its not the same as watching live, but unless they lost the feed for the whole arena, you should be able to still go back and watch every match. Nothing like having technical issues in the middle of the action, but don't give up on it. $25 for the next 2 weekends, including archived video you can go back and watch whenever and all 4 SS is a helluva deal, even if not perfect.
