IMO, debit card is safer as it allow one limit/cut losses from start
u only loses how much u have in your card
while credit card is sky the limit, unless one go consciously goes set the limit low low like I did when most ppl dun.

For credit cards, the merchants' amounts are not deducted immediately. The banks can stop the payment to the merchants.

This owner of the card can approach "Korean Style Clothes Bang",  한국식 옷방 and communicate with them. Provided he can identify this party.
