I have no unread messages on Discord, I reply to anyone within 24-48h - Otherwise with a ticket on my store I reply every week (done today).
For inbox access unfortunately when I created the accounts it used a different password for the email access, instead of adding both password on 1-line...
Most accounts I built are using mail.tm as inbox, you can send me a message on Discord with your order ID and I can give you the passwords for the inbox access - Unfortunately they do not use the same password (which is fixed in future accounts, but I have thousands of stock using 2 passwords)...
