There is no reasonable evidence to suggest that I am not the account holder, and they haven't made any attempt to take any common sense steps like asking "Can we call you on the phone?"  "Can you tell us the last 4 digits of the bank account you used to deposit/withdraw last time", etc.  I answered tons of questions about the kraken account itself, even details dating back many months. For them to conclude that I somehow know those details without being the rightful account owner would mean they concluded the account was hacked weeks earlier and the attacker locked himself out but only after saving all these details or else having compromised my email and many other accounts.  It's totally absurd. 

I don't know how to "keep at them" when all I can do is post a ticket where my messages just get dropped into a black hole with no response.  Do you have any suggestions on how to contact a real person?  Like by telephone for example?  Where else can I "keep at them" and how?
