How to come back to a closed ticket?

Once a ticket is closed you can no longer comment on it. If the issue is still there or came back, open a new request for that ticket: support sees the link to the previous ticket and does not have to ask everything again.

When you'll need this

A problem was considered solved, but it happened again.
The ticket was closed, but your question is still open.
A new question came up on the same subject and support should see the history.

What's important to know

The Open request again button appears only on closed tickets (done and canceled).
The form is short: you only have to give the reason. The department, topic, priority, and the fields you already filled in come from the previous ticket.
If the topic of the previous ticket is no longer available, the portal asks you to choose a new one. If the new topic has required fields that were not there before, you have to fill them in.
Attachments of the previous ticket are not copied: add new ones if needed.
The new request is a separate ticket named like Продовження #123: …, where the number is the closed ticket's number.
If the ticket already has an open request, a Go to the request → link replaces the button: write there.
Support decides whether it is the same problem. If so, the ticket often goes back to the same assignee.
