I can still remember that time where my account also got hacked by this stupid Phoenix Miner shits. I don't even know what that means or at least I just know that it is a miner that's all.
They've said already the way to retrieve your account and I already sent you a PM into what I've done when I experienced the same thing. Sending a signed and verified message here is the best thing and if you still have that (which is I think you have) then you're good. I still can't forget what I did after seeing the my account got locked. I needed to get my 8 yr old laptop with a broken screen just to recover my signed Bitcoin address there

Just wait for at least 2 weeks I think because that is the number of weeks I waited before I got my account back. You will get yours so no worries

. Thanks again for those who helped me back then

Whenever I see those posts, most come from low-rankers but once in a blue moon would see Legendaries. One spotted earlier today.
Do you have any malicious browser extension or using an easily-bruteforced pass by any chance?
