I've got an answer from the customer support when i made a report in-game, but they immediately put the issue as resolved and didn't ask any more questions. I mean, it's great that they answered fast, but having a look at the video clip would answer all those questions and give proof to my allegations. Should i open another ticket through the link you gave me, or just deal with the already open case? It seems to be the same address, so i guess i should just see what the CST will say.
Anyways, thanks for the infos.

I'll do that. It's just that it kind of worries me that you guys don't ask for proof or anything other than saying you'll investigate it. It feels like on one hand you're saying you're investigating to calm me, but on the other you'll say "we don't have proof of this players actions hence we will not take further measures" without even asking if i've got some proof. I've got video and exchanged messages, and i'm just waiting for CS to ask for it, or tell me were to send it. But then they just say "we're checking it" and mark the issue as resolved. And the PS4 is constantly recording, so it's kind of hard to assumer there ISN'T video evidence.

I mean, it just feels like you're setting yourselves up to not do anything unless ALOT of other players report the same guy for the same reason. It's kind of weird to me.
Anyways, thanks again. I'll see what customer support says as i,ve brought this same issue with them.
