Finish and verify the customer action
-
Wait for the confirmation page, updated conversation, email, or account message before repeating the action.
-
Confirm the customer, company, site, DSE-###### ticket, and visible status are the ones you intended.
-
Save the confirmation or reply on the same ticket when more information is needed.
-
Contact DSE immediately if account or ticket visibility includes unrelated customer information.
Final verification
Before you leave this guide
- Confirm context. Recheck the DSE domain, signed-in account, company or site, ticket number, device, and request type shown on screen.
- Confirm the result. Perform one harmless verification and make sure the visible status matches what you expected.
- Keep the reference. Save the DSE-###### ticket number, confirmation, or other safe reference needed to continue the same conversation.
- Stop on a mismatch. Do not repeat a high-impact action. Preserve a safe screenshot, note the time and exact error, refresh once, and update or open the correct DSE ticket.
