Yes do this - cheap and quick ( and it feels good doing it!).You don't really need any legal references, you need to write a letter stating the terms of your agreement i.e. refundable deposit on her cancellation, clearly set out when she notified you of cancelling, date of the party, then give your bank details and address and request payment within a reasonable period of time, say 14 days. State that if payment is not received within that time, you will make a claim via the Small Claims Court (an online application you can make yourself) and the fees for that will be added to the claim.
