Account Stolen (Vellor#5334)

So yesterday, I was messaged by an added friend on my discord friend list. He said something about some beta testing for a game. I clicked and downloaded the thing, and ran it. It logged me out, but I was able to log back in for a little before i got permanently logged back out. I submitted a report and I need help from people.

1. How long does it take for Discord to investigate and return my account? (if possible)

2. I have some evidence that this account is mine (e.g. screenshots of me changing passwords in the past, phone number still on account). If discord denies my request, what do I do? there is serious info on that account and I dont want it on the wrong hands.

3. Not a question, but be wary not to click on sussy links!
