Paypal charge back for unauthorised use of credit card

[sexybumsaustralia]

Are any other members having any problems with Papal chargebacks for un authorised use of credit cards, in 10 years I had never had one and in a few weeks I have had 2.  Not happy about paying for an item and shipping costs then refunding money to the buyer due to an unauthorised payment that does not need be proven and then to add insult being charged a $15.00 fee on top.  I am worried that I am getting scammed and would like any genuine feedback from other sellers that have recently had any similar problems or suggestions. First item was shipped by Australia Post Ebay parcel with tracking however since chargeback all details on the Australia Post website have vanished and I have been unable to get any response from them.  

Cheers, Simon.

You will win if you have Paypal seller protection, which sba should have for that value.

The problem lies with items that aren't worth paying the extra postage for. I self-insure for lower postage value.
