Ring the desk.
The desk that answers is automated. Anything it hands on is read by a person.
What happens next
Say what keeps not getting done, in your own words. Nell, on the Enquiries desk, answers first and opens a folder for the job. Leave an email address. A receipt reaches your inbox straight away.
A person reads anything that needs one, and you have a proper answer in the morning.
It helps to have the job, the deadline and the drawing to hand, if there is one. If you remember something later, reply to your receipt. It lands on the same desk.
