That's a chargeback; it could be that somebody has use the buyer's card to make a payment, or that the buyer has not recognised the item on her card statement and reported it as unauthorised.
Sellers are protected from a chargeback. You just need to provide PayPal with your proof of posting slip for that package. They should be asking for this in the message you've received.
If you can't provide this you will lose your money and be charged a £14 admin fee.
The buyer hasn't gone through eBay because an unauthorised payment is nothing to do with eBay, they don't deal with the financial side of things.
