I purchased an MP-3 from your company about a month ago. I used it only 3-4 times then I suddenly got shaky screens. It doesn't work at all even if recharged. I bought it from Korea via e:market. I want an after-sale service, and would like to return it to your company. Please advise your address and telephone number.
이런 정도로는 답변 받기 어려울 것 같군요. 해외구매 및 지불에 대한 증빙. 일자 등 자세한 reference info가 있어야 할 듯 합니다.
