Bittrex Error "Something went wrong. Please try again in a few minutes."

I was out for some family stuff and couldn't login to my account for 3 days, I came back after 3 days and tried to login to my bittrex account and it gave me this error which I included in the subject as well "Something went wrong. Please try again in a few minutes", I am way more worried and contacted on their live chat and they said that my email does not exist on exchanging platform and I should first register, Although I am registered on bittrex support and more than 2 weeks ago, I sent them 3 in 1 selfie which their support requested for accounts over $1000, Because my account was locked and they needed it, So I sent them and after 24hours it was back on, I was using it perfectly fine, This happened when I didn't used this account for 3 days, It is registered on my name and everything else, If it was "hacked" then I would be hacked from all other exchanges where I have accounts plus I have 2FA everywhere and every piece of information for 2FA stored offline. My guess is that the employee actually saw the amount I had on the exchange and took the benefit and took over this account, Because when I check that ticket on which I was asked that 3 in 1 selfie, I cannot click that employee's name anymore, Mayb he got fired for stealing or I don't know what reason, But I was not hacked AT ALL! So if anyone around here can help me out in this matter, I would really appreciate, I would be dead broke if this happens cause I kept most of my money on bittrex exchange account. I even sent them proof of my old logins on my email. Now I am waiting and they are just saying they will resolve this and i should be patient, How can I be patient when all of this hard earned money is on stake? It is not even my fault, If I was hacked, It would have been my own luck but if its exchange issue then they should resolve it at ANY COST!
