Ticket
The CS dept is currently swamped with alot of Tickets. Also it depends what you put in a ticket for. If it is for a refund, then it will take a bit for them to get to you as there is alot of those currently.
If it is something more serious. You can post it here – https://forum-en.gw2archive.eu/forum/support/account/Tickets-for-Review-3-days-older-Part-2-merged – and Gaile can look into it for you.
If it has to do with your account being hacked, unfortunately they are inundated with requests at the moment. I think they said it would take several days at minimum, though 9 days at the moment seems a bit excessive
