When should I ask that my ticket be escalated?

you believe your problem has not been resolved to your satisfaction, or if the ticket is taking a long time (more than two or three business days - Monday through Friday) to be resolved, you should call the Service Desk and follow up on your ticket.

If you believe your situation warrants, ask that your ticket be escalated.

Explain the problem to the Service Desk Agent and - if needed - push to have increased attention paid to your ticket.
