You refused to avoid AoE, died twice, refused to be resurrected and let the group kill the mobs without you twice while you are running from the ress spot to the group. I do not know what you have told the group, but I am going to assume based on what you have shared with us, that they probably thought you were trolling or something. It does not matter how you were grouped with those players, actions like that can still get you kicked.

I think everything would have been resolved if you talked with the group after your first wipe.
