Burn Notice season 3?

I was watching burn notice season 3, and the last episode I saw was when Fiona's brother was back in town from ireland and someone was trying to kill her. Was that supposed to be the finale? I looked for the schedule and I don't see any new episodes. Looking here ( http://www.tv.com/burn-notice/show/69107/episode.html ) I see that there are more, but I cant find them on my TV... or anywhere
