Printer Credit Refund

You tried to print your assignment at the university library, but the printer jammed and took your credit without printing anything. The assignment is due this evening and you have no credit left. Speak to the library assistant: explain what happened, ask for your credit to be refunded and request help printing now.

Hi, excuse me, sorry to bother you just before closing. I've just tried to print my assignment on the printer near the entrance, but it jammed halfway through and nothing came out. The problem is that it still deducted the credit from my account, and that was the last of it. The assignment is due tonight, so I'm a bit stuck. Would it be possible to refund that credit, and could you help me print it on a different machine before you close? Thank you so much, I really appreciate it.
