Why every tencent games are full of hackers?? 24/7/29

I lost my backpack, vest because of a dam hacker. he’s shooting me through a wall and this game doesnt have hit markers. so how did he know that he hit someone and keeps tracking me through a wall?? and i wont get my things back. hope theres a better anti cheat system. 2nd: i lost everything again due to the god dammit hacker and why do i need to wait a minute for the kill cam?? cant u just release the killcam instantly and return my stuffs if im killed by a damn hacker?? stop disgust free to play players, ok?
