Am I in the wrong?

I was in the random Summoner's rift game mode, I had gad good dealings in there alot in the past and people generally listened when people claimed areas in the beginning of the match. I had wanted to play Teemo top, and I felt this was an easier way to get a chest since getting s on certain champs is next to impossible... So we get into the choose your champion -screen, I call out top the second you can write. I look at the chat, seems to be a group of friends, they said the word topa and used plenty of XD's... I began to suspect they were going to ignore my call, so I said it one more time to make sure and I got no reply... then the guy who first mentioned topa out of the what was clearly a group of friends chooses Ilaoi, I think, ok, is there an ilaoi jungle? Then the game starts, I run to top first and of course Ilaoi follows me, I ping her to leave and she tells me to "Shut up", her friends making XDs in the background. I just had it, I refuse to have my game ruined by some butthats, I clearly state in the chat, that since Ilaoi is acting like a butthat, then I will feed. I hate it when entitled players think they can ruin other people's games and get away with it, she must have thought that I would cave in and go to jungle, No, I am a terrible jungler. So there it goes, I feed the enemy Jax, still stating the reason why I am doing what I am. Am I in the wrong here? Should I let people like them push me around?
