How To Redirect all my “feed” subscribers to one feed

I seem to have accidentally created several different feeds & my google webmaster page is showing different subscriber numbers for all of them. I installed the plugin to try to redirect all my feeds to feedburner but that didn’t seem to work. I am pretty clueless when it comes to this stuff, can someone help me with easy directions for redirecting all of my feeds so all my subscribers are subscribed to one and I don’t lose any people? I’d like to delete the unused feeds if possible but I have no idea how! Help! ??
