How to report someone for teamkilling

As the topic says, is there anything that can be done? It seems like a person has to team kill you multiple times to get a boot option, which doesn’t help with people who try to steal flag caps and so on.

Go to there name in the leader board, click A I believe or just view there profile and report player for unsporting behavior. A friend of mine and I had ourselves teamkilled in Breakout.
