Suspected Hacker(s)

Hey there, earlier me and some buddies were playing on the US East Coast 3 server. We had made a small house, with a couple doors in it. All the doors were closed, and I was afk in the house for a couple of seconds to run and grab my phone. When I came back, there was two guys in the house killing me and walking through doors. They managed to kill all 4 of us, take all of our stuff, and leave. As they left, they opened the doors that were closed and left them open.

What do I do/how do I report this? I have one of their names.
Thanks.

could/can you open those doors that they opened? May be possible that they placed their own.
