This is another simple and easy guide for people like me, who can never remember URL's. Logging a ticket with Episerver DXC's managed services team is pretty easy. You log tickets via the online portal here:
The portal's log in page should look something like this. When you sign up with DXC you should have been given one (or more) support accounts. If you haven't got one of these and you need one, in your monthly DXC call I suggest you raise it :P
One thing to note, the portal doesn't have a forgotten password feature, so if you forget your password, it's a little more complicated than clicking a resend password reminder, so make sure you use something you won't forget! Otherwise, make sure you have the support number to hand :P Logging a ticket is as simple as clicking the 'New Service Request' button and creating a new ticket.
Someone from Episerver usually gets back to you the day you raise a ticket, however, I have found that it can take 3-4 days to get a request to be actioned after raising a ticket. In the beginning, when you're setting up DXC for the first time, I would definitely factor this turn around time into your planning. After you raise a ticket, you'll get an email and from that point forward you can manage your ticket via your inbox, rather than needing to go into the portal again. Simples!
