Credit Card Chargeback

Hi all,


Not sure on what happens here, situation is as follows


Ebay member purchases an item from our store, must have used a credit card through paypal to pay for item, either way PayPal set these funds as cleared.  This was back on the 28th Feb.  Item was sent with Aust Post e-parcel tracking with signature and delivered a couple of days later.  Buyer has never left any feedback (as is more often the case these days)


 


Fast forward to today, I get a message from PayPal stating that charge back has occurred due to the card holder claiming was an unauthorised transaction.  I have so far now sent proof of delivery by means of tracking number as well as a copy of the delivery screen with the persons signature on it.


 


I have also tried to call the number in the ebay sale only to be initially told that this person is not known, I advised who I am and asked if the address is correct, person told me is the correct address (so I know was delivered to this address) however when I then asked if they were aware of this issue with the transaction I was very sternly told where to go.


 


Where do I stand with this do you guys think.  I have as far as I can tell done everything by the book in so far as sending to the registered address, I have tracking and signature (of course there is no way I can state the signature belongs to anyone in particular as ID is never asked for)  Do you think I will be covered under the PayPal protection system here.


 


Is not a huge amount but it really irks me when a seller does everything by the book and can still run this risk.
