But was your account hacked or did the exchange stole your money? Why did you reported the account as hacked?
let's say that i have trusted a official channel and some 3rd party not related to them(let's admit for a moment that the admin of the official group is not affiliated with them) got access to my account. but if that was the case they would have secured my other funds. like any legit exchange out there. but they did not do that. they let him further steal all of my funds so this is a sign of bad intention and a inside job.
No offens, but this actually looks like your fault, you did not secure your account enough. You did not have 2fa on, did you?
