I placed the order with Gmarket using my VISA credit card, payment was authorized by VISA. Few hours later I received an email saying that they can't process payment until I call VISA and request authorization number and provide it to them in email and placed my shipment on hold. I have been using VISA buying online from many countries and this is first time I hear that I need to trace my transaction between seller and VISA. I am going to dispute my VISA payment and ask VISA to reverse it. Not even going to get involved in debates with Gmarket, It is pure scam for money.
