Selling on ebay is a pain. Some times you meet people who complain to first run you out of business, second trying to get something for nothing, Third, they think you are some big department store who can afford a loss because being on ebay is expensive.
Close all bank accounts that you have with paypal because ebay owns paypal and the two of them are just into collecting fees and do not care if you sell the product or not. Ebay and paypal are a machine so if you close out your bank accounts, all bank accounts listed with paypal this way they can not back charge your account. You will have to pay ebay, mail them a money order.
People are nasty. Good luck.

Remind her that you explicitly stated in your listing that there are no returns or refunds. Assuming you provided clear pictures of your items, she doesn't have much room to complain. You always have to be careful before making a purchase online.
