How do I report obvious bots ruining my games?

I just played a 3v3 game with two people who had very similar names. They refused to say anything and just ran straight under the enemy towers all game. I reported them at the end of the game, but when I went to do another game I was with two different people, but with the same similarities in their names. I tried to talk to them with no reply, so just dodged because I'm not going to play this game with bots. Can I do anything else besides reporting to make sure that crap doesn't happen at least from that person?
