I got twice automatic answer and since that time nothing. I try 8 time to withdraw. Nothing. First time 9.12.2017.
Since you've been waiting for so long, try sending a private message to this user
Bitstamp-Domen on reddit with your concern, user ID and ticket number if you have. He is actively replying to those who have issues in the site including email confirmation, withdrawal, and deposits. He might be able to help you.
Thanks for the tip. I m going to send a message.
P.S:It is not about withdrawal only but about confirmation mail (withdrawal verification). It is strange that confirmation mail regarding help ticketing is working, but I never got real answer concerning this issue
