She doesn't need any information, just tell her to use the refund option in the details of the transaction when you paid in her paypal account.
Personally I think you should not have had to wait for a refund for her to get a refund from RM, she should have refunded you first and then sorted that out.
If she does not give you a FULL refund then file for item not received via the resolution tab in your paypal account and escalate the dispute to a claim.
