求救!!有關paypal的問題,請高手幫忙

對方的退款原因是 : 信用卡被盗用,這項是未經受權的交易,信用卡公司强行申請退款.

I think you did the right thing. there have been a lot of scams where the buyer credited your account then reverse credit when the item is sent. if you did not transfer your money to your bank you would be out of pocket now. if the buyer wasn't happy with your product he would have contacted you for resolution firt.

退款的原因是甚麼?
如果需要退款就要他把貨品寄回給你
你在退給他吧 但把paypal的手續費跟郵費等扣掉
