When did support get this bad

I’ve been trying to recover my account for a few days now. The last time I played was before BfA dropped. I haven’t gotten a single reply from support except the one email asking for more information which I provided. I provided my government credentials, character and realm information, a purchase order involving the account and another account that I’m still friends with. How do I get some help around here man because I just want my account back and I cant get it back since I no longer have access to the email or phone I originally used for the account 4-5 years ago.
