First of all. Please do not accuse other players by name on the forums. Report them using proper channels:
Second: could the “teleporting” your clanmate reports be caused by lag or something - the witness’s screen froze long enough for the culprit to run away (really takes only a second) so it looked as if they had vanished into thin air?
Third: I understand you’re upset, but please try to communicate your grievances in a more understandable manner. Take your time, collect your thoughts, think what you’re writing, and we’ll be better able to advise you, too.
