You can view any tickets you have raised in the Customer Portal by clicking the 'Tickets' tab or 'My Tickets' icon.
You are taken to the Tickets page on the customer portal. To check out a ticket, simply click on it.
In the ticket, you can view any activity or updates that has been made. Furthermore, you can add updates of your own through responses or the ticket details on the right column, close the ticket, add people (cc them into alerts) and check who is the Agent assigned to the ticket.
If you are complete with viewing your ticket, you can click on Home to return to the home page of the customer portal or Tickets list to view your other tickets.
On the Tickets page, the tickets listed can be filtered. Open and Pending from Date Created is the default setting.
To change the filter, select the Open or Pending drop down where you can change it to All Tickets or Resolved or Closed.
The same goes for Sort By...
