Hello, so I cannot seem to find the ticket number. I did the lakehouse fundamentals certificate through our USAF partner program. Im not sure I ever received a ticket number though. This is the email I received and did the fundamentals about 2 days after:

Limited-time offer: If you earn your Lakehouse Fundamentals accreditation by February 28, 2023, we’ll send you a Databricks certification voucher ($150 value) in March. You can use the voucher to schedule and take a selection of Databricks certification exams before August 1, 2023
