Alright, I'm appreciate everyone come to reply on this post while I'm still waiting someone from grapeshot give me an answer, I swear I didn't use any exploit personally(Guilottine exploit),same with other third party plugin. I did check my ally and my company, none of them get banned but only me. As someone said, I may do something in game and it's not allowed, but honestly i didn't know the reason i got banned because there's no message leave to me. Anyways, thanks everyone involved this post with me, I hope the community managers will check my post.
My level before i got banned is around 77
