Bittrex complaint: Crypto funds being held hostage

I cannot access my email account because my domain for my business no longer exists. The email associated with that domain holds my cyrpto funds at Bittrex. To complicate matters, I also have an account with my current email with Bittrex. So when I tried to change my business email to my current personal email, Bittrex wouldnt allow it. I asked why they couldnt merge the accounts as they are both my accounts, personal accounts, nothing related to business names or anything like that, but they couldntwoudnt do it.
When I asked what I need to do to get my crypto funds changed from the email I cant access they said I would have to provide a new email as well as identity verification, which of course was fine. I did all that they asked and then the agent out of no where said that the matter needed to be handled by a specialist. I now was talking with a new agent who said I was writing about a ticket that was the account I wanted to use not the one I cant access. I was very clear what I was trying to do but they dont seem to be listening. Now it has been 17 days and the last response i have had was 6 days ago. They wont even tell me what I need to do or direct me what they require.
